1. The drive through cashier at Hardee's in West Lafayette Indiana ca 1993
    In college my friend was driving me somewhere and decided to be a dumb teen. He went to the drive through and said, "I'd like one french fry please." Without skipping a beat the cashier said "that will be 4¢, please drive around." He accepted a dollar, returned 96¢ and handed my friend a small french fry bag with a single fry. To this day I am amazed by this whole experience.
