documents: #Person1#: Do you carry black ink? 
  #Person2#: The ink should be next to the paper clips and thumb tacks in the stationary section, sir. 
  #Person1#: I've looked for, but I didn't see any black ink. 
  #Person2#: Then I'm afraid there's none in stock. 
  #Person1#: Well, I'll settle for blue-black. I'll also take a dozen airmail envelopes. 
  #Person2#: They come in packages of ten or twenty. 
  #Person1#: Give me a package of twenty, then. And where do I find shoelaces? 
  #Person2#: On counter three. 
  #Person1#: Thank you. I never can find my way around this store. 
  #Person2#: I know. It took me three weeks, and I work here.
