An old and very good friend of mine told me he had an unpleasant experience.He went to

a famous jewelry shop and (1) to be shown some gold necklaces.(2) examining several, he decided to buy a gold necklace with a precious stone, and asked (3) he could pay by cheque .The assistant said that was quite in order，(4) the moment my friend signed his name, he was invited into the manager' s office. The manager was very polite，(5) he explained that someone with with exactly the same name (6) had given them a worthless cheque not long before.My friend got very angry (7) he heard this (8) said that he would buy a necklace somewhere else.When he got up to go, the manager told him that the police would arrive at any moment and he had better stay (9) he wanted to get into serious trouble.Sure enough, the police arrived soon afterwards.They were polite too, but explained that a person (10) had used the same name as his was responsible for a number of recent robberies.
