Clerk: Good morning, sir. Can I help you?
Customer: I want to make inquiries about leaving my car with you. You see, I’m going abroad, I don’t want to take the car but I’ll need it when I get back.
Clerk: I see, sir. Well, we can offer you full parking facilities for as long as you wish.
Customer: Good. I’m going to Athens for about a couple of weeks.
Clerk: Right, so how long do you want to leave the car with us?
Customer: Well, I’m flying to Athens on the 5th and coming back on the 19th -- that’s fourteen days, isn’t it?
Clerk: That works out at fifteen days parking, sir. Let me show you our scale of charges. We have a minimum fee of 6.50 pounds but for fifteen days it would only cost you 24.75 pounds.
Customer: It says 23.10 pounds here.
Clerk: No, sir, that’s for fourteen days. If you’re going to be away for fourteen nights, you wouldn’t be picking up the car for fifteen days.
Customer: Hmm -- fifteen it is then.
Clerk: Now, if you’ll just come this way, sir, we’ll complete the booking form. Could I have your name?
Customer: Brown. Donald Brown ...
Clerk: ... and the make of car, sir?
Customer: Just a Mini Metro.
Clerk: Mini Metro. And the colour? We get rather a lot of Mini Metros.
Customer: It’s a sort of greenish-grey. I suppose you’d call it green really.
Clerk: Green. What’s the registration number?
Customer: Oh, KTY630Y.
Clerk: And your car key number?
Customer: I say, is this all really necessary?
Clerk: Afraid so, sir. Security, you see.
Customer: Oh, all right. It’s FL243.
Clerk: FL 243.
Customer: Look here, this isn’t going to take longer, is it?
Clerk: Only another minute or so, sir. Your departure date is May’5th, I think you said.
Customer: Yes, yes, the 5th, that’s a Friday.
Clerk: Friday, 5th May. Now what time is your flight, sir?
Customer: Ten to twelve, I think. But I’ll have to check in about half an hour beforehand.
Clerk: Well, we like customers to check their cars in here at least twenty minutes before check-in time. We have a minibus to take you to the airport. It’s only about ten minutes drive.
Customer: So, I ought to be here about ten past eleven.
Clerk: Well, it’s safer before that. We do get very busy. And you’re returning on the 19th?
Customer: Yes, that’s right.
Clerk: And how would you like to pay, sir?
Customer: Oh, by cheque. Who do I make it out to?
Clerk:  Gatwick Parking Limited.
Customer: And it’s 24.75 pounds.
Clerk: That’s right, sir. I’ll just give you a receipt.
Customer: Don’t bother, I can’t wait. There’s a traffic warden coming down the street and I’m parked on a double yellow line.
