Quote from Frasier in Maris Returns
Niles: I have to cancel lunch. Frasier: Can't you see her after lunch? Niles: I have patients. Frasier: Before, then. Niles: [as Niles enters the waiting room] I'm sorry, this just won't work out. Peggy: You know, you could at least give him a chance. It's his first day!
