write a complaint letter on the topic that the prompt below specifies. The letter should have all the required parts. It may follow any letter block format (Full block, Modified Block, or Semi- Block). (writing a complaint letter): You have recently had a business dinner gathering, along with your company's management team, at a local restaurant. Unfortunately, nothing went well during that lunch: dinner took much time to be served, and when it was served, it neither matched invitees' order nor abided by minimal requirements of taste. Besides, waiters never seemed welcoming. One of them did not even apologize after spilling tea on one of your invitees. Write a complaint letter to the restaurant's manager, requesting him or her to refund you, as well as apologize to the invitees, who were so dissatisfied with the restaurant's bad service.
