Dear Sir, 

I am writing to you to complain about a in your restaurant. 
On December 16th, I was in your place to eat. When I arrived, I waited 30 minutes for a waiter to come. After we ordered the food, we waited an hour or so before it was brought to us, lunch time. The food came in a deplorable condition, and besides being cold, the meat was expired. When we asked to talk to the boss, the waiter answered in a rude and unacceptable manner.
I trust you will take the complaint seriously and give a reasonable explanation. In addition, I inform you that I filed a complaint with Consumer Protection and I will sue.

Yours sincerely
Răzvan Crețu.
