There's a funny story that has circulated among my family members for years. I have no idea whether or not it's true, but it's funny enough to repeat even if it isn't. But I really, really, really, really hope it's true. So we'll say it is.
My mother worked at a company where they took their breaks at scheduled times. You didn't just go take a smoke break any old time you wanted it, because that meant one less person running a machine or packaging fruitcakes, and the whole dang system would break down.
One day one of her co-workers started for the break room with a dollar in her hand. On her way, she stopped off at the restroom.
When she reached the break room and started to use the vending machine, all she had in her hand was toilet paper.
