      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."
