There is this good ol' barber in some city in US. One day a florist goes to him for a haircut. When he is about to pay the barber, the latter replies: 'I am sorry, I cannot accept money from you. I am doing 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 a dozen roses waiting at his doorstep.
This event is repeated till an Indian software engineer goes for a haircut. When he pays him, the barber tells him, 'I am sorry, I cannot accept money from you. I am doing community service.' The next morning, when the barber opens his shop, he finds a dozen Indians waiting for a free haircut.
