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?quot;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."
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."
