A young man hired by a supermarket reported for his first day of work. The manager greeted him with a warm handshake and a smile, gave him a broom and said, "Your first job will be to sweep out the store." "But I'm a college graduate," the young man replied indignantly. "Oh, I'm sorry. I didn't know that," said the manager. "Here, give me the broom - I'll show you how."
