M: Good morning, this is Spa Heaven. How can I help you?
W: Well, basically, I think I'm too tired and looking for some way to relax.
M: OK, sure. Did you know that we recently have a special offer which allows non-members to use our facilities without having to pay the membership fee?
W: Oh, that's great.
M: Yeah, but the offer is just until the end of this month. Anyway, let me tell you a little about the facilities at Spa Heaven, and you can decide what interests you. First, we have a fitness center where you can have a weight training so that you can lose some weight.
W: And that sounds good, but I'm not really interested in getting fit. I just want to get rid of my tiredness and be energetic.
M: In that case, you may be interested in our sports facilities...
W: Mm, well, I like to go swimming and I find that helps me relax. Do you have any swimming facilities at your place?
M: Certainly. We have two 25-meter pools here.
W: Can you tell me how much that costs?
M: Well, for non-members, it costs just $10 for each time.
W: I think I need to do something more relaxing, though, you know, like meditation. Do you have anything like that?
M: Well, meditation is part of our yoga classes, which we have every day. And during the special offer period, non-members can take part for just $35 per class.
W: OK, thanks very much for your help. I'll come down this afternoon and arrange a yoga class.
M: Sure, I'm looking forward to seeing you then.
