Taking the fun out of flying
The CFI is an absolute pain. He used to moan at me if I was flying above 7000 feet, complained if I visited a grass airfields (banned me from flying for abit for doing that once). He seemed to take great pleasure in taking all the fun out of hour building which should be the most fun. Flying to different places, getting a coffee with a friend then flying back. He wouldn't allow that.
demand ruled were followed when they weren't written anywhere, and always have to be right, if he couldn't prove it or you didn't believe him it was an "EASA rule" I'd ask him to find it and he never would even try to look, as he knew he was wrong
