A bus stops at a small bus stop. A man is hungry and he wants to buy some cakes. It’s raining hard. He doesn’t want to go out in the rain. He sees a boy. “Come here, boy!” he cries. “Do you know how much the cakes are?” The boy says yes. He gives the boy four dollars and asks him to buy two cakes. “One is for you and one is for me.” Three minutes later, the boy comes back. He’s eating a cake. He gives the man two dollars and says, “Sorry, there is only one cake left.”
