M: Good morning.
W: Good morning. How can I help you?
M: I understand that the school organizes ... umm, trips to different...
W: Yes, we run five every month: three during weekends and two Wednesday afternoon trips.
M: What sort of places?
W: Well, obviously it varies, but always places of historical interest and also which offer a variety of shopping, because our students always ask about that ... and then we go for ones where we know there are guided tours, because this gives a good focus for the visit.
M: Do you travel far?
W: Well, we’ re lucky here, obviously, because we’ re able to say that all our visits are less than three hours’ drive.
M: How much do they cost?
W: Again it varies between five and fifteen pounds a head, depending on distance.
M: Ah ha...
W: Oh, and we do offer to arrange special trips if, you know, there are more than twelve people.
M: All right. I’ll keep that in mind. And what are the times normally?
W: We try to keep it pretty fixed so that students get to know the pattern. We leave at eight-thirty a.m. and return at six p.m. We figure it’ s best to keep the day fairly short.
M: Oh yes. And how do we reserve a place?
W: You sign your name on the notice board. Do you know where it is?
M: Ah ha. I saw it this morning.
W: And we do ask that you sign up three days in advance so we know we’ ve got enough people interested to run it,
   and we can cancel if necessary, with full refund of course.
M: That’s fine. Thanks.
