Plenty of research has shown that people often buy more than they planned
on, once they get in the store. Customers certainly won't buy anything
extra if they never even set foot in the store.

Because they set the card reader on the pump up to be really finicky
- about a third of the time I get "Card unreadable, See Attendant"
error which gets you inside the store. The attendant doesn't have any
problems reading the card at the counter...

My experience has been the exact opposite. When my debit card mag
strip was too worn for any store cashier to accept with a swipe, the
gas pumps always took it. Since that is basically what I use it for
95% of the time, I went about a year without replacing it even though
it was a PITA those few times I used it in a store.
