Frasier: You know, I just feel like being on my own tonight. You don't mind, do you?
Niles: Of course not, I'll just see you at Cucina for lunch tomorrow.
Frasier: Well, maybe we ought to play that by ear as well.
Niles: As you wish.
Frasier: You're not upset, are you?
Niles: Frasier, I'd have to have a pretty fragile ego to be upset just because you want to take some time away from me.
Waiter: Do you want to pay?
Niles: Separate checks, please! [turns away from Frasier]
