What problem are they talking about?

W: Smith, do you have a minute?
M: Oh, hi, Mary. Sure. What’s up?
W: Well, I’ve been meaning to talk to you about the situation in the office.
M: I’m not in there very often. It’s so noisy that I can’t work.
W: That’s what I want to say about. We need a quiet place to work in. But Jack has a lot of visitors. People are going in and out.
M: Has anybody spoken to him about it?
W: No, not yet, but someone’s going to have to.
M: I think so, but who?
W: What about you?
