Nie wiem kto siedzialby z zona w restauracji i pisal list z zazaleniem ale masz:
I feel that I need to place a complaint about the service of the staff in your restaurant. After arriving, I had to wait half an hour for a table I've booked the day before. Furthermore, I was served a cold meal and the change I was supposed to be given was treated as a tip and taken by the waiter. I demand that the staff are punished for their unproffesional behaviour.
Yours sincerely, (wstaw imie)
