Many people have to work on the weekend. Some people do not mind. Other people think it is terrible
(可怕的).
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 24th, 1986, he went to the office to do some work. When he got on the elevator (电梯),
it stopped between floors. Mr. Coates could not get out of the elevator. He started to shout, but no one heard
him. Then Mr. Coates remembered that it was a holiday in England. No one was going to come to work until
Tuesday.
There was nothing for Mr. Coates to do. He had to wait until one of co-workers came to work and found
him. With nothing to eat or drink, Mr. Coates ended up sleeping for most of the time.
