M: Two six two four three double four. David Carter speaking.
W: Hello, David, it’s Joyce—Joyce Cook.
M: Hello Joyce, how are you?
W: I’m very well thanks. How are you?
M: Oh, not so bad, you know.
W: Good. I rang to ask if you know anything about hotels on the Costa Brava.
M: No, I’m afraid I can’t be of very much help to you there, why?
W: Well, it’s just that we’ve been thinking of taking the family to Spain this summer and at this rather late stage we’re trying to organise ourselves a suitable hotel. But I thought that you’d been to the Costa Brava.
M: I have. Several times. But I’ve always taken a tent and do it the hard way.
W: Oh I see. I didn’t realise that.
M: Yes. Great one for the open air, you know.
W: Oh. It must be nice, but we could never contemplate it with our lot. We’re terribly disorganised as a family, you know, and we’d be in chaos in no time. And in any case the car isn’t big enough to get all of us in and camping equipment as well, so we simply must find ourselves a nice hotel where they’ll put up with noisy kids.
M: Mm. You have got a problem. I tell you what, Joyce. It’s just occurred to me—Mr, and Mrs. Simpson from over the road have been to that part of Spain several times, and I seem to remember them saying they always use some hotel.
W: Do they?
M: Yes. At least I think that’s what they said. I’ll pop round later this evening, and if they do know anything that might be of use to you I’ll get one or the other of them to give you a ring.
W: Would you? That’s very kind of you.
