M: Excuse me, I'd like to exchange the T-shirt. It was a birthday gift, but I really don't like it. I prefer something plainer.
W: I see... Well , why don't you look around? I think the black color is better on you. The yellow one is also good, but you should pay extra 10 dollars if you buy it.
M: I prefer the yellow one, I think it's looser and longer, so it will be more comfortable.
W: OK, no problem. I will switch them for you.
