A man went to a fast-food restaurant to buy his lunch."Hi," a worker said."May I help you?"
"I'd like a hamburger, large chips, and a Coke," the man said.
"Anything else?" the worker asked.
"No," the man answered."That's it."
"Is that for here or to go?" The worker asked.
"To go," the man said.
The worker put the man's lunch in a bag. The man took out his money and paid for his lunch.
"Thank you," the worker said. "Have a nice day."
The man took the bag and walked to a park. He sat down and opened the bag. He was surprised.
There was no hamburger in the bag. There were no chips. There was no Coke. There was only money
in the bag-a lot of money! The man counted the money. Two thousand dollars! Why was the money in the
bag? Where was the man's lunch?
The manager of the fast-food restaurant needed to go to the bank. He put two thousand dollars in an
envelope (信封). He put the envelope in a bag and put the bag down. The worker gave the manager's bag to
the man by mistake. So the manager had a hamburger, chips and a Coke, and the man had two thousand
dollars. What should the man do?
