Man, one of the card strips at one of the pumps didn't work, and I was all paranoid that someone put one of those scams up where they read your card strip information and then are able to duplicate it onto another card. It's true! It happened to a friend of mine! IF your card doesn't work at one of the pumps, I would cancel the transaction and go to another pump or another gas station pronto! Hopefully it's fixed by now...
