It was Friday evening and shopkeepers in Grimsby came to the Midland Bank to put theirmoney into the night safe. But later that evening the night safe disappeared and with it 4,000pounds. Every Friday evening the shopkeepers put the money they take during the week into thenight safe. They don't want to leave it in their shops, but the bank closes early. The night safe isoutside on the wall and the money they put into it goes into the bank. But on this Friday evening thepeople who came along the street with their bags full of money dropped15them not into a night safe,but into a box that belonged to Mr. Michael Bell.
Mr. Bell, who makes radios and televisions, had the idea when he saw two men outside thebank one evening. When he came home from work, the two men, who were, apparently16shopkeepers, were putting some money into the night safe. He made the box at home and painted it.
When it was ready, he took it to the bank and hung it on the wall next to the night safe.
On the front of the night safe he painted the words: "Please use the new night safe. This oneis out of order." Then he went round the corner and waited for the shopkeepers to arrive. Helistened while they dropped their bags of money into the box. When it was full, he quickly took itdown and went home with 4,000 pounds.
Mr. Bell is very-clever and his idea was good, but not perfect.17 Now he has time to think of other ideas. He's in prison for stealing.
