I wouldn't have paid in advance. If the reader doesn't work, I leave and go somewhere else.

It would probably depend on my mood if I was stuck in that situation whether I went to get the quarter or not.

But if I wanted my quarter, then you'd damn well better give me a quarter. If it's "just a quarter" and no big deal, then reach into your own damn pocket and give me one of yours. You know the cashier was thinking, "what a pain in the ass, I don't want to go through the hassle of the paperwork for a quarter." If it was the cashier wanting a quarter, you can bet your ass they'd be screaming to get their quarter back.
