[speaker001:] I think I going to need some iced water too. Is there an extra charge for that?
[speaker002:] Yes, we charge 50 cents for 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 anything for the sauce, pepper and napkins?
[speaker002:] No, there is no charge for those.
