Help with line meaning
On two occasions, Claude Rains (Captain Renault) uses the word "precedent," and I believe he is using it mistakenly, which is hard for me to believe because he is, after all, Claude Rains. Yet, it all rings in my ears as a misuse of the word.
First time: "Oh, a precedent is being broken." Shouldn't it be, "A custom (or tradition) is being broken." Or, "A precedent is set!" Because Rick is doing something against his own policy, that is sitting with guests.
Similarly, later on when Rick takes the bill, 'Another precedent gone."
Anyone??
Thanks.
