Massachusetts allows the fire marshal of each town decide if its citizens are competent enough to pump gas safely. The entire state of New Jersey is full serve. If I was truly saving money, I'd say OK, but I see proof that gas can be sold with an attendant for the same price as me freezing my (insert favorite body part here) off in the winter. Ed |

If you are calling a disabled pump (i.e., defeated locking nozzle) a safety feature, then you must be calling all gas station attendants who use locking nozzles stupid?

The reason I don't patronize the self-checkouts at HD and my local
grocery stores is twofold: a) I'm not as fast and accurate as the checker, and b) self-service checkout stands take away jobs. With jobs disappearing as fast as the U.S. budget surplus I don't think it's a very good idea to facilitate the process. Besides, why should I have to do the work when I don't get a discount? |

How about the fact that self-serve gas stations in the other 47 states aren't going up in impressive balls of flame with any regularity? I hate having to fill up in self-serve states. Here in NJ, there have been a few pushes in the past (mostly by the oil companies) to get NJ to change the law prohibiting self serve. But it's been at least 15 years since they tried. I think this is because they discovered that it doesn't save them any money, and may actually end up costing money. Don't believe me? Most gas stations around here employ 1 or 2 people at any given time to man the pumps. They usually have 6 or 8 pumps, that may or may not have a roof over the top to protect them from the elements. Most self-serve stations I have been to in other states STILL employ 1 or 2 people at any given time, PLUS they have AT LEAST 8 pumps, sometimes 12, 16 or 20, usually much newer and cleaner WITH a room overhead. The roof and the newer facilities are to attract customers who don't want to be out in the rain pumping gas with dirty pump nozzles. They still need someone inside to take the money, BUT since customers pumping their own gas are slower than a station attendant pumping gas, they need more pumps, they need the roof, they need to maintain the pumps better - all this cost them money AND you still have to get out of your car when it is cold and get your hands smelly to pump your own gas. But that's just my opinion, I could be wrong. -Chris |

The time it takes to stick the nozzle in the tank is insignificant, compared to the time it takes for the pump to deliver fifteen or twenty gallons of gas. Plus, it takes a *lot* more time to pay an attendant, than it does to just swipe a MasterCard in the pump. I try to buy all my gas at stations with credit-card pumps because it saves so much time. Have you ever been in "the line" to get gas at Costco? Usually it's some really sloooow person who pulls up, futzes around in their cab for a few minutes, comes to the pump and then fishes for their card, reads the pump directions over several times, places the card in the slot all four possible directions before getting it right, wonder why no gas dispenses and then proceeds to re-read directions, etc. etc. etc. But you are correct otherwise, pay at the pump is so much more convenient that dealing with cashiers and lines inside... -Bruce -- Regards, Doug Miller (alphageek-at-milmac-dot-com) -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Trent I saw this on our news in CT. It did not happen here but they made a big deal about getting back into the car and getting out to take the filler out. Women are more prone to do static because of the stocking they wear. They also got into filling gas cans in the back of a pickup as fumes can collect there, just like when you fuel a boat. I once picked up a nozzle from the pump, hit the start button and had gas spew out as the previous user jammed the handle in the "on" position. No damage, but it did stink from the spill. As for the latch device, I know some states do not permit them, but a station in my town just got all new hoses and nozzles and they all have the latch. That is one reason I like that station. There pumps also have a higher capacity than many of the newer self serve models. Keeping this on topic, I filled the tank so I could drive to the lumber yard to buy some wood. Ed |

wrote: You know, _Pride_ used to be the worst Sin. From the Fifth Century B.C.E. we have the warnings of the Greek's about Hubris which became codified by Pope Gregory in the Fifth Century C.E. as Pride and so on to Shakespeare's warnings in the tragedies a thousand years later, so on to Raskolnikov and Dostoevsky's portrait of the self absorbtion that must become madness. The common thread is that Pride is the progenitor of the notion that the other is as nothing in comparison to the self and that it can be objectified to the point where there is no obligation to acknowledge the other as part of the same world that the self inhabits. This thinking allows the Hubrist to violate the commonly held beliefs of the society that he dwells in, at his whim, when it is these commonly held beliefs which describe society, and their violation is the basis of Sociopathy. The primacy of Pride in the order of the Deadly Sins is not a mere description of its position in a numerical order but is rather a call to recognize it as the basis for all of the other sins. It is then Pride which allows someone to claim as his own that which does not belong to him, in violation of any concept of morality that has been expressed in Western Culture for at least twenty five hundred years. Seen in this way, this taking is not a small act. Although the sum may be small, the implications are vast. Should we teach our children that stealing a small sum is of small consequence or should we teach them that stealing is wrong? Regards, Tom Thomas J.

The automatic shutoffs often do not work. I've personally gotten a gasoline bath at least a half dozen times...while holding the handle down. Then you must pump gas from some pretty poorly maintained places. In the past 25 years since self-serve became the vogue, I can remember only one time when the cutoff didn't work, and that was only after it had activated once and I was trying to get the numbers to come out to a currency round number. I suspect that the local fire marshal would shut down a place rather quickly were it found that its automated cutoffs were inoperative; that's a hazard whether you are forcing people to get cramps in their hands in the freezing cold while being forced to act like metal stops or whether you have metal stops holding the nozzle open. |

I'm not sure what world the copylefted Trent lives in. In my world, I have yet to see an automatic cutoff not work on initial fill (only time I've seen it happen was when continuing to fill after the pump cutoff), nor have I encountered any gas pumps anywhere that don't allow one to continue filling after the initial cutoff -- there are times when this is not just to round out the sale but because the cutoff works prematurely and there are many more gallons before the tank is actually full. Also, I've never seen anyone take that much time pumping a few cents extra to round out the sale -- I see much more time with fumbling with credit cards, adjusting the hair before moving the car, etc. Just the other day I had the cutoff initiate immediately; seems I have to back the nozzle out just a bit or the backflow initiates the cutoff. Not very practical to have the pump shut down immediately upon cutoff. Not to mention, situating the kids back in their car seats - why do they need to get out while you take five minutes to fill up the tank. I've rarely waited in line for diesel for that matter. I try to plan my fuel stops so that I have the option to bail and get fuel later if there's a wait. I hate waiting. Lines are a hassle I put up with when the price is 20¢ less a gallon - that's the difference around here between BJ's (or its ilk) gas and the regular stations. Up in PA, the difference isn't so staggering (~5¢), but the lines are shorter so it balances out. Me too. However, in my area (Tucson) the difference is on the order of a dime, except at Arco that doesn't take credit cards, thus one either has to mess with their cash eater or have to pre-pay to pump. Only thing I hate worse than waiting is having to pre-pay to pump gas. I avoid prepay like the plague. You gotta run in and give the cashier some money, run out fill the tank, run in and get change - and have to wait in line each time. The credit card (debit, etc.) at the tank are great.

After several failed attempts with both cel phones /and/ static sparks, they found that it takes a REALLY exact mixture of oxygen and gas fumes to spark a fire. And cel phones CANNOT start one, even under perfect laboratory conditions. Just to set the record straight, like all legends, there is (was) a grain of truth to this. In the old days (we're talking before the invention transistors here), 2-way radios were built in two parts, a control head that mounted under the dashboard, and a radio unit, that mounted in the trunk. These radios were big clunky tube things that used many hundreds of volts to generate their RF, and were often mounted near the gas tank filler tube of the car. *AND* the vacuum tubes usually got the required 'high voltage', from a device called a 'dynamotor'. Think of a 12-VDC *BRUSH*TYPE* motor driving a generator that produced several hundred volts. Usually there was near-continuous arcing going on at the dynamotor brushes, *regardless* of whether you were in transmit or receive. Switching from receive to transmit did two things. First it switched the high voltage to the transmitter with an open (un-enclosed) relay contact that often times arced horribly (think massive spark). Second, it switched the antenna wire from the receiver to transmitter (again with a massive spark). So now you have all the conditions for a good explosion: 1. enclosed space (the trunk) 2. ignition source (the sparking relay) 3. proximity to fuel (leaking filler tube) And as I recall, all the 2-way radio user manuals of the time cautioned about filling up and transmitting at the same time. YUP. These were also relatively _high_power_ transmitters -- 50 watt, 100 watt, or even more. there was a non-trivial risk of a 'random' piece of metal(anywhere _near_ the transmitting antenna) acting as a -receiving- antenna with enough efficiency to generate enough voltage to jump a relatively small distance to 'ground'. That big bumper-mount antenna was only a foot or so away from where the gas fumes were pouring out of the gas tank. Not a _probable occurrence, but the 'downside risk' was "bad enough" to justify 'unreasonable precautions' to avoid it. However, nowadays, with today's modern solid state, low voltage electronics, all switching is either done by hermetically enclosed reed switches or by solid state switches so there is no possibility of getting an arc to ignite gas fumes. The -other- risks, of stray RF pickup/rectification, and jumping to ground do remain. *Virtually* non-existent, however due to the much, *MUCH* lower power levels used -- modern cell-phones transmit with 0.6 watts _maximum_, and as much *less* than that as will suffice to maintain communications. (the cell tower actually 'tells' the phone to reduce power, till its at the 'minimum' effective level. Not to mention the fact that a cellphone doesnt have an antenna switch since it's full duplex. I think the first 2-way radio with hermetically sealed relays first shipped in 1970 (Motorola Micor) but many poorly funded police departments and cab companies continued using the old equipment well into the '80s so it wasnt all that long ago that a car could still blow up. So yes, it's an urban myth today and deserves to be roundly debunked, but at one time it really was possible to blow up a car simply by talking on your radio. But this is way way off topic now... It is *still* a concern, for vehicles running 'higher power" business-band (or other, e.g. "ham") 2-way radio systems, . It is only cell-phone technology where it is a true non-issue. as noted, getting _way_ off-topic. |
