M: Hi, Cathy! I heard that you’ve been to London on business for a number of times, but never have I been there before. So I really need to ask you a few questions before I go there.
W: Sure, my pleasure.
M: Which hotel do you recommend to me? I’ve heard much of Holiday Inn. What’s it like?
W: It’s nice there. It’s in the city center and has all the usual business facilities a businessman needs. They provide first class service, I think.
M: Oh, good. So I’ll make a reservation for a single room there. Now, what’s the best form of transport to get to the hotel from the airport. Should I take a taxi?
W: Well, you can, but you don’t have to. There’s an excellent subway system.
M: Mmm... can you tell me something about the business hours? I mean, what time are the banks open?
W: The hanks? They open at half past eight and close at four thirty.
M: I see. And are they open on Saturday, too?
W: I’m afraid not. And I’d better warn you, the shops close very early in London. During the week they’re open until half past six, but on weekends they close at four.
M: At four! My god! Now, what’s the weather like at this time of the year?
W: Well, it’s usually warm But sometimes it turns very cold and wet. So don’t forget to take an umbrella before you leave the house. By the way, when are you going on this trip?
M: Oh, not until the middle of the month. September 15th, I think Anything else you want to advise me on?
W: No, nothing I can think of now. It’s a nice place, peaceful and calm, and the people there are friendly. I’m sure you’ll enjoy your stay there.
