One day a florist goes for a haircut. After the cut, he goes to pay the barber and the barber replies: "I am sorry. I cannot accept money from you, I am doing a community service". The florist is happy and leaves the shop.

The next morning when the barber goes to open his shop, there is a card and a dozen roses waiting at his door. A butcher goes for a haircut the next day and he also goes to pay the barber and the barber reples: "I am sorry. I cannot accept money from you. I am doing a community service". The butcher is happy and leaves the shop.

The next morning the barber goes to open his shop and there is a thank you card and a package of steaks waiting at his door.

The next day a Fireman goes for a haircut and goes to pay the barber. The barber replies: "I am sorry. I cannot accept money from you, I am doing a community service".

The next morning when the barber goes to open his shop and there are two dozen other Firemen waiting for free haircuts.
