A well-known New York contractor went into the tailor's, donned his new suit, and left his old one for repairs. Then he sought a café and refreshed the inner man; but as he reached in his pocket for the money to settle his check, he realized that he had neglected to transfer both purse and watch when he left his suit. As he hesitated, somewhat embarrassed, he saw a bill on the floor at his feet. Seizing it thankfully, he stepped to the cashier's desk and presented both check and money.
"That was a two dollar bill," he explained when he counted his change.
"I know it," said the cashier, with a toss of her blond head. "I'm dividing with you. I saw it first."
