When told you need to spend a certain amount to use your credit card, to you scramble for another item, or just walk away?

Everyone’s hit that purchasing roadblock: You want a soda for a buck fifty, have no cash, and the cashier informs you that you need to spend at least 3 dollars to use your card.

What do you do in that situation? Do you scramble for another item to meet the limit, or do you walk away?

If you’re a cashier, how many people do either or?

I usually scramble to meet the limit myself, but a few days ago I walked a way. I felt like a douche, but it’s a stupid rule.
