写一篇五十字英文版的餐厅投诉信
Dear Manager,
I am writing to express my disappointment with the service I received at your restaurant. The food was cold and the service was slow. Additionally, the waiter was rude and unhelpful when I asked for assistance.
I hope that you will take my feedback seriously and take steps to improve the quality of your food and service. I look forward to hearing from you soon.
Sincerely,
[Your Name]
