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 that often unless I have to go shopping.
M: But how could the bus service be improved?
W: Well, they should turn up on time. I mean when you see the timetable, you think "Oh well, five minutes to wait" but 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. Fortunately, a girl who works in his office often gives him a lift into work. But when he does need to use it, he’s often angry at it. Once he waited up to 50 minutes at the station for a bus. There should be some ways of warning people when a bus is not going to arrive and certainly much more frequent bus services.
