Many, many years ago my Great Aunt Bess was the Roosevelt's housekeeper for their house in Long Island. My Grandmother made the trip to America for a visit & stayed with them. When she was going running a bath she was told to only use one teaspoon of bath salts. She thought to herself 'Bess isn't usually stingy, I wonder what that's about?' & promptly tipped quite a bit more into the bath.

When the bubbles hit the ceiling, she knew she was in trouble.
