Mrs Smith had bought a nice new T-shirt for John, but when he tried it on it didn't fit.

It's Saturday evening and Mrs Smith had to return the T-shirt.

Mrs S: Excuse me, can you help me?

Shop Assistant (1) : Yes of course, what can I do for you?

Mrs S: I bought this T-shirt for my son this afternoon, but

it doesn't fit him, it's too small.

Shop Assistant: Do you want to change it or get a refund (2) .

Mrs S: I'd like to change it for a larger size. Do you have these in large?

Shop Assistant: I'll just check. Let's see, yes we have large or extra large, and which would you prefer?

Mrs S: I think large will be fine, it's for my son.

Shop Assistant: That's fine, if it doesn't fit just bring it back again. If you take it to the customer (3) service desk, they'll sort it all out for you.

Mrs S: Thank you. Just as a matter of interest do you give refunds?

Shop Assistant: Yes, of course. You can bring any clothing items back up to three weeks after purchase (4) , but you must keep the receipt (5) .

Mrs S: I see, thanks again.

Shop Assistant: You're welcome ...
