Exercise 20. Complete the text with expressions from the box and answer the questions after it. Translate the text.

I'll never forget my first day at that office. I was told to arrive at 8.30, but when I got there the whole place seemed to be empty. I didn't know what to do, because I was offered no information about the building or where I was going to work, so I just waited around until some of the secretaries began to turn up. Finally I was shown a dirty office on the fifth floor, where I was given a desk in a corner. Nothing happened for an hour, then I was given some letters to type on a computer by one of the senior secretaries. This wasn't very successful, because I had never been taught how to use a computer. By lunchtime things hadn't got any better, and I decided that. I wasn't being paid enough to put up with this nonsense, so I walked out and didn't go back.

1) When was the man told to be at work? 2) What did he do when he arrived and why? 3) What was his workplace like? 4) Why wasn’t he satisfied with his workplace? 5) What task was he given? 6) Why wasn’t it a success? 7) Why did he think he wasn’t being paid enough? 8) What did he decide to do? 9) Was he right?
