What is the man going to do?

W: What can I do for you, sir?
M: I’m looking for a jacket for my son.
W: Come with me, please. Here are the jackets for boys.
M: The black one looks nice. How much is it?
W: Twenty-five dollars.
M: Oh, I am afraid it’s too expensive.
W: What about the blue one over there? It looks nice, too. And it’s a little cheaper.
M: But it’s a bit too small. Have you got a bigger size?
W: Sorry, we haven’t. But we’ll get some soon. Will you come back next week?
M: All right. I’ll come back then. Thanks.
