[speaker001:] Do you carry black ink?
[speaker002:] The ink should be next to the paper clips and thumb tacks in the stationary section, sir.
[speaker001:] I've looked for, but I didn't see any black ink.
[speaker002:] Then I'm afraid there's none in stock.
[speaker001:] Well, I'll settle for blue-black. I'll also take a dozen airmail envelopes.
[speaker002:] They come in packages of ten or twenty.
[speaker001:] Give me a package of twenty, then. And where do I find shoelaces?
[speaker002:] On counter three.
[speaker001:] Thank you. I never can find my way around this store.
[speaker002:] I know. It took me three weeks, and I work here.
