answer: #Person1#'s watch stopped running. #Person2# checks it and tells #Person1# it needs a new battery. #Person2# introduces their service and #Person1#'ll get the battery here.
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. It seems that it just needs a new battery.
  #Person1#: Oh, really? I got some water on it last week and I was afraid that it might ruin the watch. How much is a new battery?
  #Person2#: It's $5 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 3 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. Can you leave your watch here until 5:00 PM?
  #Person1#: OK. See you then.
