What exactly does the man want to find out?

M: Hello, Mrs Smith. I’m from the Daily Mirror. And I’m doing a report on public opinion about the city bus service. So, what do you think of the bus service?
W: The bus service? Actually I don’t use it that often unless I have to go shopping.
M: What’s ... how could the bus service be improved?
W: Well, they could turn up on time. I mean you look at the timetable and you think, oh, well, five minutes to wait, and it turns out to be an hour.
M: Do any other people in your family use the bus service?
W: My husband. He uses it more often. But fortunately a girl who works in his office often gives him a lift to work. But when he does need to use it, he’s often angry at it. Once, he waited up to fifteen minutes at the station for a bus. So I think there should be some way of warning people when a bus is not going to arrive and certainly much more frequent bus services.
