By that reasoning, every full serve gas station should charge you for a
fixed amount full tank, not the actual number of gallons they pump into
your car. Yet somehow they stay in business by charging you just for
the amount you actually receive...

Seriously Where does one find full service gas stations any more?

Both situations are self-regulating, driven by the consumer's desire to
minimize the number of trips he makes to either facility. Sure, there
are times when you want to top off your gas tank before it gets really
low, but by and large we buy a tankful to save ourselves the hassle of
frequent visits to the station. I imagine it's the same with propane.

For that matter, it's true of all retail establishments. If you go into
a store to buy a lottery ticket, do you think the proprietor breaks even
on the nickel he gets for the transaction? Some purchases are losers,
from a strict accounting standpoint, but who would shop at a place that
insisted on a minimum order?
