What happens if you fill your car up with gas using the pay-inside option, and then your card doesn't work? Or you don't have the cash you thought you did? And the gas is already in your car? Do you have to wash out the hot dog machine? Do they take your license plate number and put it on your tab? I ask not because of personal experience, but because it occurred to me today that I am 25 years old and have no idea what would happen in that situation. Enlighten me.
