One day I was in a Mervyn's at the check out counter. A guy and his girlfriend were trying to return 2 pair of new Levi's -- no receipt, no tags, not even a bag.
The cashier said that they would have to issue a refund via mail. The guy said that this would be unacceptable as he wanted cash, now -- and asked to speak to the supervisor. She said, "I am the supervisor."
He then said to her, "Well, I don't think you have too much class."
