If you mean Brian C, then I agree, he’s s fabulous trainer and a close personal friend of mine. We joined on the same day and did our 757 course together.
Your list of gripes are wierd I agree, but I’m not sure they’d wind me up to a great degree. Maybe bring it up in the PFDB? You may get an insight into his or her thinking? And if you brought up how it pissed you off, they may change their style in future. If you didn’t say anything, then they won’t ever know.
