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 payment 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 haircut.
