One lady was so paranoid about a crew's honesty that she left a small pile of change on a table every day while they worked there. The supervisor noticed her counting the change at the end of the day and told the crew about it.
Soon, everybody was putting a penny, or a nickel, or even a quarter into the pile....just to mess with her.
