Junies Instructor?

Junie has been training for a few years.
Who is his instructor? How as a instructor could you handle a student like that? I know from experience that martial arts changes people for the better.

How can an instructor put up with a jerk like Junie?

BFH

He is showing his ass to get air time? Maybe his 'fame' will land him a few fights?Unless he lives with his instructor I can't see this being his norm in the gym.
