M: Good morning, madam! Can I help you?
W: Oh, I do hope so. I have to get to Manchester today and my own car has broken down. Do you by any chance have a car available?
M: For how many days, madam?
W: Three, just until the weekend.
M: And what sort of car did you have in mind?
W: Well. That depends a bit on the price. But I normally drive a Cavalier. Do you have anything like that?
M: Yes, certainly. That’s Group C which includes Cavalier and Sea-arrows.
W: How much are they?
M: Well, for three days, you would have to have it under the unlimited mileage conditions, which will work out cheaper for Manchester anyway. Let’s see, Group C, three to five days hire with unlimited mileage is 53 pounds per day.
W: I see. Does that include everything?
M: It includes third party insurance, but does not include value-added tax, petrol or CDW.
W: What’s that?
M: CDW? Oh, that’s to cover you in case you damage the hired car. Third party insurance only covers you for damage to another vehicle. For Group C car is 6 pounds per day.
W: OK. I think I’ll have the Cavalier.
M: Right. Could I have your driving license please?
W: Certainly. Here you are.
M: So, it’s Ms. J. B. Couty.
W: Yes. That’s right.
M: And the number is 509024bc9cs, expiring the 1st of July, 2015. And do you want to take it immediately?
W: Yes, I do, please.
M: Lovely. Well, if you could, just initial that box there for the CDW, and that box there to confirm you have no driving convictions. Thank you. And then sign there. Great! That’s it!
