I don't think that's off topic at all. I agree that you really did dodge a bullet. For an interviewer to treat you with such disrespect over something which is so trivial and inconsequential is an immediate red flag. The purpose of an interview is not just to assess, but to sell the role to the candidate. "Negging" is an antagonistic interaction which is utterly inappropriate for the professional environment.
