M: Could I have my bill, please?
W: Certainly, sir. Here you are.
M: Could you kindly explain this to me? What is item 7?
W: Yes, sir. That’s the service fee, 15 per cent.
M. Oh, I see... I think there has been a mistake here.
W: I’m sorry, sir. But what seems to be the trouble?
M: I think you’ve charged me twice for the beer. Look, item 2 and item 6 are both about beer.
W: I’ll just check it for you, sir. Please wait here for a moment.
M: OK, no problem.
W: You’re quite right, sir. The cashier made a terrible mistake. I think you will find it correct now.
M: Good, thank you. Now, can you take my credit card?
W: I’m afraid we don’t accept credit cards.
M: Oh, dear. Can I pay by traveler’s checks?
W: Certainly, sir. We’ll give you the change in local currency if that is all right.
M: You needn’t worry about that. There won’t be much change.
W: Thank you, sir.
M: You’re welcome.
