【正确答案】
[范文]
Dear Manager,
I am a resident living near your restaurant. I'm writing to inform about the low-quality food and poor service you offered me several days ago and hope you would investigate the matter.
Firstly, your waiters and waitresses were impolite to guests. For example, one waiter even turned a deaf ear to our request when we asked for some hot water. In addition, the sanitary situation was far from satisfactory. What's worse, the food served was badly made and of low quality, in which we even found sand and little stones.
I trust you will now consider this matter seriously and make an effort to prevent the recurrence of this kind. Thank you for your attention and kind consideration.
Yours Sincerely,
Li Ming
