I tired to explain to one sales clerk at the long gone Handcock's Fabric store that she gave me too much change back. I gave her a $10 and she gave me back change for $20. She said no you gave me a $20 bill. I kept insisting I gave her only a $10 bill. She said fine, took the change back and handed me a $10 bill. She said now we are even. I just left.
