Roz: Niles! Every time I give you my chair, you wipe it off first. It's just insulting.
Niles: For your information, I was reaching for my cell phone.
Roz: Oh. I'm sorry, Niles. I stepped out of line. See you later, Frasier. [Roz leaves]
Frasier: Bye bye, Roz.
Waiter: [answering the phone] Café Nervosa.
Niles: [on the phone] Yes, this is Dr. Crane at Table Seven. Could you send someone over to dust off my chair?
Frasier: Oh, for God's sake! I'll do it!
