The problem is not just with you but think of all the other students that he is teaching, he aught to be questioned.
Maybe he is just winding you up?
I remember in that lovely book (whose name I have forgotten) where "the instructor lit a match in front of (my) nose during a difficult landing. I was to thank him 15 years later".
I personally had an instructor who used to offer me a wrapped sweet just as my hands and feet were dancing all over the place landing a microlight! Pretty cool guy though, one of the best if a bit unorthodox.
