Can I help you?
Oh, I'm just looking, thanks. Well, actually, I'm looking for something for my girlfriend.
And what sort of thing are you looking for?
I don't really know. A dress?
Right. What color does your girlfriend usually wear?
Oh, dear...
OK, what color are her eyes?
Green.
Right, purple suits people with green eyes. Now, what size is she?
Um, well, sort of, she isn't very big, but she's not particularly small. That'll be medium then.
Well, we have this rather nice silk evening dress here...
Good, I'll take it. Thank you. How much is it?
That's 70 pounds, sir. How would you like to pay?
Seventy? By credit card, please.
Fine. If you could just sign...
Here you are. Goodbye.
