遇到不满意的事情和对待需要投诉时，礼貌地说比较奏效。而且有趣的是，你可能先要说SORRY，再提出你的投诉，这样显得很有教养和礼貌，你的问题才会得到更圆满的解决。 (来源：英语论坛 http://bbs.englishcn.com)

　　比如，在商店里，收款员找错了钱，你可以说：

　　'Excuse me, I think you've given me the wrong change'

　　或者 'Sorry, I think this change is wrong. I gave you $20, not $10.'

　　在酒店里

　　房间的调温器坏了：'Excuse me, but there's a problem with the heating in my room.'

　　'Sorry to bother you, but I think there's something wrong with the air-conditioning.'

　　失窃了：'I'm afraid I have to make a complaint. Some money has gone missing from my hotel room.'

　　房间没有整理：'I'm afraid there's a slight problem with my room - the bed hasn't been made.'

　　当人们发现自己错了而道歉，一般都会说SORRY，然后再提出把事情做好的解决办法。

　　比如对应上面对调温器的投诉：'Excuse me, but there's a problem with the heating.' 或者

　　'I'm sorry - I'll get someone to check it for you.' 或者 'Sorry to hear that - I'll send someone up.
