A young man hired by a supermarket reported 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 university 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.”
