Niles: Frasier, you are not a prisoner of your character. You can decide right now that you're going to be the flexible one here. Pay the money, and go.
Frasier: I could break my pattern.
Niles: Yes.
Frasier: I could just pay the money, without proving to everyone that I'm right, without teaching them a lesson.
Niles: Exactly. You can do it.
Frasier: Sir? I'll have you know, I am leaving, with time to spare.
George: Congratulations.
Frasier: Since you cannot understand the moral code for which I stayed here, I am sure you must be perplexed that I am leaving before the twenty minutes is up. Suffice to say, I am the bigger man for it. And you, and your nefarious policy may now carry on, in what is highway robbery in the truest sense of the expression. Here is your ticket, and... your ill-gotten two dollars.
George: Four dollars.
Frasier: Four dollars?
George: You went over twenty minutes. It's two dollars for each portion of twenty minutes.
Frasier: But I already backed down!
George: Well, if you had spared me the speech, you would have made it out in time. Tough break, huh?
Frasier: Indeed. [rolls up his window] Hold on, Niles.
[Frasier floors it, smashing through the exit barrier as he drives off]
