M: And Pacific tours. How can I help you?
W: Good afternoon, can I speak to Mark please?
M: Speaking?
W: Oh, hello Mark this is Linda from Johnson and sun’s events.
M: Hello Linda, what can I do for you?
W: I was just wanting to clear up a few details of the conference events we’re organizing
M: Right, what do you need to know?
W: Well, first I’ve got to have numbers delegates to the conference, their husbands, our wives and so on for the transport as much as anything else.
M: So far we’ve got 183 who’ve booked up and we might get a few more.
W: Does that include husbands and wives as well?
M: Not really. I’ll email you the exact number because I haven’t counted them yet.
W: Fine.
M: And they’ll be six guest speakers.
W: Thanks.
M: Yes, who want picking up from the airport by car not in your fleet of buses.
W: Right, you’ll let me know when they’re arriving won’t you?
M: Just as soon as I know.
W: Now special events, you wanted a local style dance for the opening ceremony didn’t you?
M: It would be great. I’m sure everyone will enjoy it.
W: And we’ll have to fly the dancers in specially.
M: Sure.
W: And then at the welcoming feast there’s going to be a piano performance, right?
M: Yes, but we’ll have to contact the airline company about it. They’re sponsoring the event.
W: So we’ll send the Bill direct to them for it.
M: You could do.
W: Well. That’s all my queries for the time being.
M: Okay, if you need anything else just pick up the phone or drop me an email.
W: I will, thanks, bye.
M: Bye.
