     When Laura was a university student in the city, she found it very difficult to live on her grant when prices were going up all the time, so she decided to look for a part-time job. When she saw an advertisement in the paper for snack bar staff, she sat down to apply for the job. She wasn't sure how best to present herself on paper, so she just put down the details of her education and experience. The owner of the bar rang some days later to ask her to come for an interview the following day. When she arrived, she was nervous because she felt sure he could see through her claims to have worked as a waitress before, and would turn her down. But finally the interview was over, and he shook hands with her and said, 'See you next week, then!'
