A：Excuse me, sir. Could you spare a minute?
B：Uh, yes.
A：Do you go to work by train every day.
B：Yes. I commute five days a week by train.
A：And would you mind telling us what you think of the rail service?
B：It’s really very good.
A：Why do you say that?
B：Well, trains are frequent and come on time.
A：Which train do you catch in the evening?
B：I usually take the five thirty home.
A：And can you get a seat?
B：No, I usually have to stand.
A：Would you agree that the service is fast?
B：Yes, it’s reasonably fast but it certainly isn’t cheap. Fares have gone up 25 persent.
