M: Good morning. What can I do for you?
W: We’d like to check out now. Would you please give me our bill?
M: Certainly. Can I know the room numbers and your name, please?
W: We were in Rooms 204, 205, 206, 207, 208, 209, and 210. I’m Susan, the tour guide of the group.
M: Just a moment, please, Susan. I’ll have your bill ready in a minute. By the way, did you have dinner in the hotel’s restaurant yesterday afternoon?
W: Yes, we did.
M: Your final bill for yesterday’s dinner hasn’t reached me yet. I need to contact the restaurant to ask them to send the bill here at once. Would you please wait a minute while I ring up the restaurant?
W:  Sure. But would you mind making it quick? We are in a hurry. We’d like to go downtown for shopping or window-shopping.
M: I see. I won’t keep you waiting more than half a minute. Sorry to have you waiting, here is the bill. It totals 5,204.80 yuan.
W: What’s this item, please?
M: Oh, that’s for the long distance call to the U.S.A. Ms. Smith made last night.
W: I see. But the amount of money paid by our travel company does not include charges for phone calls. This amount should be paid to you separately by Ms. Smith.
M: I’m sorry to have included this in the bill. I’ll make out your bill anew.
W: Thanks. Do you accept traveler’s checks?
M:  Yes, we do.
W: I will tell Ms. Smith to pay the phone call after she finishes her breakfast.
M: Thank you very much.
W: You are welcome.
M: I hope all of you will have a good day!
W: Thank you.
