餐馆服务投诉信范文：如何写一封有效的投诉信

Dear Sir or Madam,

I am writing to complain about the service I received at your restaurant on Saturday night. I had booked a table for four people at 7pm, but when we arrived, we were kept waiting for over half an hour before being seated. When we were finally shown to our table, it was dirty and we had to ask for it to be cleaned.

To make matters worse, the waiter who served us was extremely rude and unhelpful. He got our orders wrong, and when we asked for some extra napkins, he rolled his eyes and sighed.

Overall, I was very disappointed with the experience, and I hope you will take steps to improve your service in the future.

Yours sincerely,

John Smith
