Many people have to work on the weekend. Some people do not mind. Others think it is terrible.
One man thinks that working on the weekend can be dangerous. He is Graham Coates. Mr Coates works in an office in Brighton, England.
On Saturday, May 24, 1986, he went to the office to do some work. When he got on the lift(电梯), it stopped between floors. Mr Coates could not get out of the lift. He started to shout, but no one heard him. Then Mr. Coats remembered that it was a holiday in England. No one was going to come to work until Tuesday.
There was nothing for him to do. He had to wait until one of his workmates came to work and found him. With nothing to eat or drink, Mr Coats ended up sleeping for most of the day.
Now Mr. Coates says, "I only use lifts if they have telephones in them."
