A waitress refuses to be on a reality show when tv stars and camermen come to her bar and asks the other waitress to step in and serve them. When her friend asks her why she doesn't want to be on that show, she says: "I think they are over".
What is the meaning of over here?
I would understand her to mean that the show is no longer as popular or "cool" as it once was, and that it probably won't be on the air much longer, so she's not interested in appearing on it.
