Retail staff may get lost having to count back your change but this story from a Burger King in the Okanagan beats them all. The till showed my friend was owed 99 cents in change. The young lady rounded it off in her head and handed him two dimes. He says "That's a mistake" and hands back the dimes. She thinks about it and rounds it the other way, handing him a dime and a nickel this time. He wishes I could post the dumbfounded look on her face when she still didn't get it.
