If an instrucotr spoke to me like that, not only would i put him on the floor, id be making a complaint to the flying school.
One of my friends had an instructor similar to the one you describe. Basically, my mate gave him a piece of his mind and got everything off his chest. No more problems after that. The same went with my Mum with her driving instructor.
Take him through all 12 rounds if he can handle it.
