Gus, a traveling salesman, stopped at a gas station to use the facilities. The restroom had two commodes, and there was a man already using one of them. They nodded at each other and went about their business. Gus finished first and as he pulled up his pants, some change fell out of his pocket into the bowl. He looked at it for a moment, then threw a 50 into the bowl.
"What did you do that for?" the other man asked.
Gus replied, "Well, you don't expect me to put my hand in there for thirty-five cents, do you?"
