Barber gives free cuts

A barber gave a haircut to a priest one day. The priest tried to pay for the haircut, but the barber refused, saying, "you do God’s work." The next morning 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 pay, saying, "you protect the public." 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 the justice system." The next morning the barber found a dozen lawyers waiting for a free haircut.
