answer: #Person2# tells #Person1# he put a buck in the vending machine but the thing got stuck. After hitting the machine, #Person2# gets the candy bar.
documents: #Person1#: Hey, man. What's up?
  #Person2#: Ah, first of all, I put a buck in the vending machine for a seventy-five cent candy bar, and the thing got stuck here in the machine. Then, I pressed the change button [Ah, man], and nothing happened. [Wow!] Nothing came out. The dumb thing still owes me a quarter.
  #Person1#: Well, did you talk to the man at the snack bar to see if he could refund your money?
  #Person2#: Yeah, I tried that, but he said he didn't own the machine, and I'd have to call the phone number on the machine.
  #Person1#: What a bummer.
  #Person2#: Hey, I have an idea. [What?] Why don't we rock the machine back and forth until the candy bar falls?
  #Person1#: Nothing doing. I don't want to be responsible for breaking the thing, and besides, someone might call the cops.
  #Person2#: Ah, don't worry. I've done it before. Oh well. Hey, hey, tough luck. Hey, here, take my candy bar. [You mean?] Yeah, the machine and I hit it off earlier today.
