题型：选择题 任务型阅读。假设你是餐馆的经理Mr Price，读了顾客Raymond Yuen 写给你的投诉信。现给他回一封email，对他的投诉作出回应。下面是投诉信原文：An e-mail to complainHere is an e-mail with a complaint from An unhappy customer in Canada.To: manager@tastytreat.com.ca Date: Monday, 7 October, 3.34p.m. From: raymondyuen@canada.net Subject: Complaint Dear Mr Price, I have eaten in your restaurant many times and have always been happy with the food and service. This makes what happened last Saturday even more disappointing. It was my son's birthday so we booked a no-smoking table at your restaurant for 7.30p.m. We arrived on time but were told that our table was not yet ready. At 8.00p.m.,we were given a table in the smoking section. I asked to move but I was told that there were no other tables. A lot of people were smoking so it was uncomfortable and unhealthy. Our first waitress, Janet, was very polite and helpful. She gave us free drinks for waiting so long. Ourfood also came quickly and looked fresh and tasty. When my wife had eaten most of her meal, she founda dead cockroach (蟑螂) in her vegetables. She was shocked and wanted to leave. At first, the waitresstold us it was a piece of garlic (蒜). When we told her that garlic does not have legs, she apologized (道歉)and took the food away. We asked for the bill, expecting not to pay for my wife's meal. Nobody came. After 15 minutes, I asked to see the manager. The head waiter told us that you were on holiday. I complained again about the horrible cockroach. He told me Janet had finished work. He didn't believe mystory and gave me a bill for three meals. I argued with him but was made to pay. The waitress, Janet, was always friendly, but I would like an apology (道歉) from your impolite head waiter and a full refund (退款) for our meal. It cost $68. Until then, I will not be eating at your restaurantor recommending (推荐) it to anyone. You can contact me at 742-3254 or through e-mail if you want more information. Thank you for your attention.
