answer: #Person2# tells #Person1# #Person2# is worried about #Person2#'s car which is in the shop. #Person1# asks #Person2# to watch out because some mechanics may overcharge people who don't know much about cars.
documents: #Person1#: Is this table on the corner OK?
  #Person2#: Sure, we can sit here.
  #Person1#: Gee, you've hardly got anything on your plate.
  #Person2#: Yeah, I guess I'm just not that hungry.
  #Person1#: What's the matter? Aren't you feeling well?
  #Person2#: Well, I've been really worried. It's my car. It's in the shop again.
  #Person1#: Really? What's wrong this time?
  #Person2#: I don't know exactly. Something's wrong with the brakes I think.
  #Person1#: Well, at least that shouldn't cost you much to fix. Parts are cheaper for all American cars like yours. Did the mechanic say how much it would cost?
  #Person2#: He said he would call me later today about the cost.
  #Person1#: Watch out, he doesn't try to take advantage of you.
  #Person2#: What do you mean?
  #Person1#: Well, some car mechanics, if they think that someone doesn't know much about cars, they might try to over charge that person.
  #Person2#: Maybe so, but I trust this man. He has done some work for me in the past and his prices seemed to be fair.
  #Person1#: Oh. That's good to know. Maybe I'll try using him in the future. By the way, do you need a ride home after class today?
