Once a man was waiting for a taxi.
A beggar came along and asked him for some money. The man ignored him. But being a professional, the beggar kept on pestering him. The man became irritated when he realized that the beggar would not leave him alone unless he parts with some money.
Suddenly an idea struck him.He told the beggar, “I do not have money, but if you tell me what you want to do with the money, I will certainly help you.” “I would have bought a cup of tea”, replied the beggar.
