answer: #Person2# is very friendly when #Person1# asks for the beer. But when #Person1# says #Person1# left the wallet and asks beer for free, #Person2# becomes not so nice.
documents: #Person1#: Hello? Um, can I get some help over here?
  #Person2#: Sure thing. What'll it be?
  #Person1#: A menu, please.
  #Person2#: We don't serve food - just the beers you see on the wall.
  #Person1#: All right. What about that one? It's German, right?
  #Person2#: Yeah, it is. Is that what you'd like?
  #Person1#: Sure, that'll do. But I'd like a cold one if you've got one.
  #Person2#: Sure thing, sweetie. That'll be $6.25.
  #Person1#: Say, you're kinda friendly, aren't you?
  #Person2#: I suppose it comes with the job. It pays to be nice to people, don't you think?
  #Person1#: I suppose it does. That's what my mother said to me anyway. Oh, wait. Wait a second. Oh, no. I can't believe this!
  #Person2#: What's wrong?
  #Person1#: I think I left my wallet somewhere.
  #Person2#: It's gotta be around here. Maybe on the floor?
  #Person1#: No. It's not there. I don't know where it could be. Any chance you can be nice and give me that beer for free?
  #Person2#: No chance of that happening. If no one's paying, I'm not so nice.
