You and a friend had dinner in an expensive restaurant last night, but it was an unpleasant experience. The waiter at the restaurant was terrible and the food was bad and overpriced. You and your friend had severe stomach-aches the following day. Write a letter to the restaurant manager and explain your dissatisfaction with the service offered by the restaurant, quality/taste of food served, complain about hygiene/cleanliness maintained in the restaurant, and so on. Ask the manager to do something about the situation or ask for your money back.
