W: Good afternoon, Davidson’s Plumbing. Hold the line, please. Sorry to have kept you waiting. Can I help you?
M: Yes. Is that Davidson’s Plumbing?
W: Yes, it is.
M: I’d like a plumber to come look at my toilet, please. It seems to be blocked.
W: But our plumber is out working and he may not be able to make it there until tomorrow. Is that OK?
M: Not really. We’re in a fix because we’ve only got one toilet. Is it possible for him to come sooner?
W: Mm. It’s not likely, I’m sorry. He’s completely tied up with appointments all day ... but look, if you’d like to hang on a minute, I’ll try to get in touch with him and see if he has a moment to spare.
M: OK. Thank you.
W: Hello ... Well, you’re in luck. He’s had a good run with his work today and his last appointment was called off, so he can fit you in at about 5 o’clock.
M: Oh, great! Could you give me a rough idea of the cost?
W: No, sorry, not until he sorts out the cause of the problem, but don’t worry, he’ll fill you in on the cost before he goes ahead with the work.
M: OK. Thanks very much for your help.
W: You’re welcome. Could I have your name and address, please?
M: Yes, it’s Mr. Ford.
W: Sorry, I didn’t catch that. Did you say Sword?
M: No. Ford. F for father, -O-R-D.
