What does Tom usually have for lunch?

W: Well, good morning, Tom. I haven’t seen you for a long time. What seems to be the trouble now?
M: I feel very tired. I’ve got a bad headache. And I can’t sleep well almost every night.
W: Have you been eating properly? Eating the right kind of food is important for your health, you know.
M: Well, I haven’t been eating too well, I guess. I have a lot of work to do, and I usually only have enough time to have a sandwich and a cup of coffee for lunch.
W: And what about dinner?
M: Sometimes I’m too tired to eat anything at all.
W: That’s too bad. You must have a well-balanced diet. But I think the most important thing for you to do at the moment is to have a good rest.
M: Yes, I see.
