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

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

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