Where is the conversation taking place?

M: There seems to be some mistakes on this bill. You charged me for a movie I didn’t watch. And this charge here...what is it?(69)
W: That’s for the room service you had this morning, sir. (68)
M: Room service? What room service? You’d better check your computer again because I think you’re mistaking me for someone else. I met a client for breakfast at a restaurant this morning.(70)
W: Oh, is that right? Let me straighten this mistake out right away.
