How about this for a radical idea. Talk to the instructor.

Perhaps something like "Hey Joe, you know the lesson the other day how
you were pretty agitated, was there some reason for that, because I
didn't think my flying was anywhere near the screaming-near-death
stage."

Voting with your feet is fine, but remember, this is a two way street,
students learn from instructors but instructors learn from students
too. If your instructor walked out on you, you'd like the respect of
them talking to you first about why, so give your instructor the same
respect.
