You do realize that you're required to show ID when purchasing food with a check or credit card (unless you provide a pin in a debit transaction) just because the local leftist brain dead teenager doesn't ask you for one when you use your credit card doesn't mean that technically you're supposed to..
Lol. In 14 years I've used cards, I have never been asked for ID.
My parents write " see ID" on the back of their cards, and still almost never get asked for I'd.
