A barber gave a haircut to a priest one day. The priest tried to pay for the haircut but the barber refused saying “I cannot accept money from you, for you are a good man – 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 “I cannot accept money from you, for you are a good man – 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 “I cannot accept money from you, for you are a good man – you serve the justice system.” The next morning the barber found a dozen more lawyers waiting for a haircut.
