Read the dialog between a shop assistant (SA) and a customer (C), then answer the question.

SA: Good afternoon. What can I do for you?
C: Good afternoon. I’d like to look for a shirt for my friend.
SA: Cotton or synthetics?
C: Cotton, please. If you have bright colors for the shirt, bring it all for me.
SA: All right, these all our new collections for the bright colors. Or you want the blue ones with the yellow stripes. It’s good for your friend, maybe.
C: Oh yes. That’s a nice shirt. Could you take it out, please?
SA: Okay, what’s the size?
C: XL.
SA: XL? Are you sure?
C: Yes, I’m sure.
SA: Here you are. You can pay it at the cashier over there.
C: How much is it?
SA: That’s one hundred and fifty dollars. Plus taxes.
C: Okay, I’ll pay for it. Thank you then.
SA: Thank you very much.
