Can I help you?
Oh, I'm just looking, thanks. Well, actually, I'm looking for something for my sister.
And what exactly are you looking for?
I don't really know. A dress?
Right. Well, what color does your sister usually wear?
Well.
OK, what color are her eyes?
Green.
OK, purple usually suits people with green eyes.
Oh, great. Purple is fine.
Now, what size is she?
Uhm, well, she isn't very big, but she's not particularly thin, either.
That'll be a medium then. Well, we have this rather nice silk evening dress here.
Good. I'll take it. How much is it?
$70. 00, sir. How would you like to pay?
$70. 00? Ah, by credit card, please.
Fine, if you could just sign...
Here you are. Goodbye.
Just a minute, sir. Here's your receipt.
Oh, yes. Emm, can she exchange it if it doesn't fit her?
