Frasier: I think I made a mistake.
Niles: Maybe it's time to back down.
Frasier: I'm not sure that I can. I am right, after all. My principles are holding me captive.
Niles: Your principles may have started this, but it's your rigidity that's kept it going.
Frasier: My rigidity? The rigid ones are the ones who operate this garage, and enforce such inflexible policies.
Niles: You've been given more than one opportunity to leave without paying.
Frasier: Yes, but that's not the point. They have to know why I won't pay.
Niles: Which you could explain in a letter. But no, you won't be satisfied until everyone either agrees with you, or has suffered for failing to.
