A man having lunch at a Chinese restaurant noticed that the table had been set with forks, not chopsticks. He asked why. The waiter said, "Chopsticks are provided only on request."

"But," the man countered, "if you gave your patrons chopsticks, you wouldn't have to pay someone to wash all the forks."

"True," the waiter shot back, "but we'd have to hire two more people to sweep the floor."
