What are you talking about? What squander? Someone does something and you ask "What was that?" Let them say "That guy hates Scheme" or "We don't know, sorry about that.", or fail to.

This much is basic human respect you give to anyone in any context.

It's not good advice to suggest any less.

When you ask that question matters.

By immediately spending more time on such nonsense you've chosen to give it top priority.

Surely you have more important things to communicate to the remaining interviewers in your interview, than someone else's behavior.

How much time do you imagine this consumes? You seem to be bringing a lot of weird ideas and assumptions to something pretty small.
