Michael had a gift card to Buffalo Wings & Rings to use up. His balance was less than a dollar under what he spent on his meal, but he put the remainder on a debit card anyway. Sure, handing over a dollar would have saved him some time in the end, but he had no way to know in advance that the employees of this particular outpost of the chain were all incompetent. When the waitress accidentally ran the entire balance on a credit card, she shrugged and made it Michael’s problem. She didn’t know how to reverse a charge. Guess he’d have to come back and use the gift card another time.
