How people think

There is a good old barber in some city in the US. One day a florist goes to him 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 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 door. A policeman goes for a haircut and he also goes to pay the barber after the cut. But the barber replies: "I am sorry. I cannot accept money from you. I am 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 a dozen donuts door. A (you know who) software engineer goes for a haircut and he also goes to pay the barber after the cut. But the barber replies: I am sorry. I cannot accept money from you. I am doing community service." The (you know who) software engineer is happy and leaves. The next morning when the barber goes to open his shop, guess what he finds there... Can you guess? Do you know the answer yet? Come on, think like (one of them).... A dozen people from there waiting for a haircut........
