听力原文：M: Hi. I have a reservation for tonight. W: And your name? M: It's Nelson. Charles Nelson. W: OK. Mr. Nelson. That's a room for five, and... M: Excuse me? You mean a room for five dollars.* I didn't know the special was so good. W: No, no, no. According to our records, a room for five guests was booked under your name. M: No. No. Hold on. There must be some mistake. W: OK. Let's check this again. OK, Mr. Charles C. Nelson for tonight... M: Ah. There's the problem. My name is Charles Nelson, not Charles C. Nelson. You must have two guests under the name. W: OK. Let me check this again. Oh. OK. Here we are. M: Yeah. W: Charles Nelson. A room for one for the 19th... M: Wait, wait! It was for tonight. Not tomorrow night. W: Hum. Hum. I don't think we have any rooms for tonight. There's a convention going on in town, and uh, let's see. Yeah, no rooms. M: Ah come on! You must have something. Anything. W: Well. We do have some rooms under renovation with just a roll-a-way bed. None of the normal amenities like a TV or working shower or toilet. M: Ah man. Come on. There must be something else. W: Well. Let, let me check my computer here. Ah! M: What? W: There has been a cancellation for this evening. A honeymoon suite is now available. M: Great. I'll take it. W: But I'll have to charge you two hundred fifty dollars for the night. M: Ah. Man. I should get a discount for the inconvenience. W: Well. The best I can give you is a ten percent discount plus a ticket for a free continental breakfast. M: Hey. Isn't the breakfast free anyway? W: Well, only on weekends. M: I want to talk to the manager. W: Wait, wait, wait, Mr. Nelson. I think I can give you an additional 15% discount and I'll throw in a free room for the next time you visit us. M: That 'll be a long time. What is the first problem with the man's reservation?
