A、They are happy to chat to him. B、They only give one-word answers. C、They have interesting stories to tell. D、They dislike taxi

W: Well, Kevin, as a college graduate, how did you become a taxi driver?
M: Well, you do it for money, obviously, like most jobs, but I enjoy it. I suppose I enjoy being a taxi driver, (19)because I can be my own boss, you know, doing what I want to do. You decide what area you’re going to, when to have a break, staff like that. (20)One thing you have to be always thinking about is where you may pick up a passenger.
   You’re always sort of scheming to make an exact bit of money. And the relationship between reward and effort is very immediate. You make the right decisions, they pay you and you get a fare.
W: How do the passenger feel when you talk to them?
M: You meet some people who aren’t all that nice, but the vast majority of people are very nice. (21)If you’re pleased t o talk to them, they’re mostly pleased to talk to you. You get a feel for people who don’t want to talk to you. Obviously the first couple of one-word answers will tell you.
W: So you always start talking?
M: I always wish people "good morning" or "good afternoon" or whatever that gets things off to a good start, because quite a few people have a general dislike of taxi drivers.
W: Do they?
M: Well, they do. I mean, the mere fact they can’t get a cab the minute they want one makes them annoyed.
