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."
