All the people who went to the new supermarket had one great hope: to be the lucky customer who did not have to pay for his shopping. For this was what the notice just inside the entrance promised. It said, "Remember, once a week, one of our customers gets free goods. This may be your lucky day!"

For several weeks Mrs. White hoped, like many of her friends, to be the lucky customer. Unlike her friends, however, she never lost heart. Her kitchen was full of things which she did not really need. Her husband tried again and again to persuade her to give it up, but she just wouldn't listen. She dreamed of the day when the manager of the supermarket would come up to say, "Madam. this is your lucky day. Everything in your basket today is free."

One Friday morning, after she had finished her shopping and had taken it to her car, she found that she had forgotten to buy some tea. She rushed back to the supermarket, got the tea and went to the desk to pay for it. As she was walking, she saw the manager of the supermarket coming up. "Madam," he said warmly, holding out his hand, "I want to congratulate you! You are our lucky customer today. Everything you've got in your basket is free."
