[speaker001:] I think I need some iced water, too. Is there an extra charge for that?
[speaker002:] Yes. We charge 50 cents for iced water.
[speaker001:] That's fine. Could you give me some more napkins, too?
[speaker002:] Sure. Do you need anything else?
[speaker001:] Yes. I would also like some sweet-and-sour sauce and pepper.
[speaker002:] I'll put all that into the bag for you.
[speaker001:] Do I owe you for the sauce, pepper and napkins?
[speaker002:] No, there's no charge for those.
