One day a florist went to a barber for a haircut.
After the cut, he asked about his bill, and the barber replied, 'I cannot accept money from you , I'm doing community service this week.'
The florist was pleased and left the shop.

When the barber went to open his shop the next morning, there was a 'thank you' card and a dozen roses waiting for him at his door.

Later, a cop comes in for a haircut, and when he tries to pay his bill, the barber again replied, 'I cannot accept money from you , I'm doing community service this week.' The cop was happy and left the shop.

The next morning when the barber went to open up, there was a 'thank you' card and a dozen donuts waiting for him at his door.

Then a Member of Parliament came in for a haircut, and when he went to pay his bill, the barber again replied, 'I can not accept money from you. I'm doing community service this week.' The MP was very happy and left the shop.

The next morning, when the barber went to open up, there were a dozen MPs lined up waiting for a free haircut.
