Local gas pumps are programmed to shut off at $75. Their assumption is that anyone who pumps $75 probably drove off and ripped off the hose, leaving it to pump out on the ground.
Of course, at the current price of gas, this means I can't pump my Suburban full of gas without swiping the card and restarting the pump.
I guess some see the tank half empty. I choose to see it half full, but I'm still irritated.
