What a grade A tosser that guy is.
You see the problem with those sort of people think they are a a superior breed and he is basically taking the piss out of you. You need to get a backbone mate and confront him HEAD on. I can tell you now if someone had said that to me when i was doing my instructor rating i would have gone into orbit. And don't just go in there and say "can i talk to you please" get in there all guns blazing and tell him what a prat he obviously is!
