A barber gave a haircut to a priest one day. When the priest tried to pay for the haircut, the barber refused, saying, “You do God’s work,” The next day the barber found a dozen Bibles at the door to his shop. A policeman came to the barber for a haircut, and again the barber refused to accept money. “You protect the public,” he said. The next morning the barber found a dozen doughnuts at the door to his shop. A lawyer came to the barber for a haircut, and again the barber refused payment, saying, “You serve justice.” The next morning, the barber found 12 lawyers standing in line waiting for haircuts.
