answer: #Person2# checks #Person1#'s watch and thinks it needs a new battery. #Person2# can offer a guarantee if #Person1# buys a new battery here. #Person1# agrees.
documents: #Person1#: Excuse me, my watch stopped running, and I am not sure what's wrong with it.
  #Person2#: Well, let me look at it. Hmm, it seems that it just needs a new battery.
  #Person1#: Oh, that's really. I got some water on it last week and I was afraid that it might ruin the watch.
  #Person2#: How much is a new battery? It's 6.99, and we not only change a battery but also guarantee it for a year. And if you have the watch cleaned here, we can guarantee it for an additional three months.
  #Person1#: That sounds like a good deal. I'll get my battery here. When will it be ready?
  #Person2#: Usually I can do it right away but now I'm repairing lots of watches and I am way behind. Can you leave your watch here until 5 PM?
  #Person1#: Okey, see you then.
