On the way out of town I stopped to get gas at the Shell station that's right by the interstate on the west side of Frankfort. Just above where a user would put in his/her credit card was this sign:

I THINK the creator of the sign meant "DEBIT" card. Not sure if this was a Freudian slip or just a case of bad spelling, but it doesn't matter as the sentence makes sense either way.
