A: Can I help you, madam?
B: Yes, I bought this sweater yesterday.
A: Yes, I remember. Is there a problem?
B: Yes, I'm afraid it's too small.
A: What size is it?
B: It's a small. Do you have a medium?
A: I'll go and check. Just a minute.
I'm sorry but we don't have this sweater in your size. But we do have this one and it's the same price. Or you can have a refund.
B: Erm...I'll take this one then, please. Can I try it on?
A: Yes, of course. The changing rooms are over there. Is everything OK?
B: Yes, this one fits perfectly.
A: Good. Do you have the receipt for the other sweater?
B: Yes, here you are.
A: Brilliant.
