A new supermarket put on a notice inside the entrance. It said, "Remember, once a week, one of our customers  gets free goods(things that cost nothing). This may be your lucky day!" All the housewives who went to the supermarket had one great hope: to be the lucky customer who didn't have to pay for her shopping. For several weeks Mrs. Blake hoped to be the lucky customer. Unlike many other customers, she never gave up hope. The cupboards in her kitchen were full of things she did not need. She dreamed of the day, when the manager of the supermarket would come and say to her, "Madam, this is your lucky day and everything in your basket is free." One Friday morning, after she finished her shopping and had taken all the things to her car, she found that she had forgotten to buy tea. She went to the supermarket, got the tea and went towards the check-out. As she did so, she saw the manager of the supermarket come to her. "Madam," he said, "congratulations! You are our lucky customer and everything in your basket is free!" Which of the following is NOT TRUE according to the passage?
The manager of the market was a clever businessman. In fact the notice for free goods was a trick  . Mrs. Blake's dream came true at last. Mrs. Blake did shopping every week in the past several weeks.
