documents: #Person1#: Excuse me, can you tell me if there is a gas station around here?
  #Person2#: Yeah, there are a few. The closest one is only a couple of blocks away. But it's a little expensive. The cheapest one is about 2 miles from here.
  #Person1#: Well, I think I should just go for the closest one.
  #Person2#: OK. Just go straight until you see the first traffic lights up there. Take a left turn and go down one block. You'll see the gas station near a post office.
  #Person1#: OK, I should be able to make it.
