One day a florist goes to the barber 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'm 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 thank you card and one dozen roses waiting at his  door.

On the second day, a cop goes for a haircut and he also goes to pay the barber after the cut.  But the barber replies: I'm sorry I cannot accept money from you. I'm doing community service. The cop is happy and leaves the shop. The next morning  the barber goes to open his shop, there is a thank  you card and one dozen  donuts waiting at his door.

On the third day, Ah Beng goes for a haircut and he also goes to  pay the barber after  the cut. But the barber replies: I'm sorry I can't  accept money from you,  I'm doing a community service. Ah Beng is  happy and leaves. The  next morning when the barber goes to open his shop.

Guess what he finds  there???
