A chocolate story

This morning, on the way to office, I was waiting in one of the trafffic signals. A six-to-seven-year boy came to my window and knocked car window pane. He was hanging some God's photo to his neck. His faciapl expression was very pittyful. He begged with his empty bowl. I felt very sad that this boy is begging at the time when he should be going to school and playing with mates. I took few moment to decide whether give some pennies or not. After few seconds he knocked my window again raising his bowl. I usually don't encourage beggars unless I am convinced that the person is really deserving.
This boy seemed to me as a deserving and instead giving money, I gave a chocolate I had. He took it with sad face and went to the car behind mine. I just observed with curiosity. For my surprise the six-year chap took chocolate from his bowl and with out eve seeing what it is, threw that under the car and went ahead begging
I don't understand what made him to throw the chocolate ! What you think ?
