Change clubs, change instructor? You don't want to be at this place. Your instructor sounds like a complete knob. This is childish behaviour and besides, you are member who is entitled to instruction and the use of the club's amenities. If you had done something wrong, a sensible, mature person would have let you known the error of your ways, get you buy into the resolution and check some time in the future, if necessary, that the lesson had been learnt. And left it at that. That was not done.

But I'd probably react in another immature way and **** the git behind bikeshed, so to speak.
