I have got a CFI with a really bad attitude. I recently had a taste of his '1950s captain' attitude. I asked for a second oppinion on something I was not happy with on an aircraft and was totally put down for being silly and over critical. I was told that all aircraft have this 'thing' that I soptted when I know they don't. He actually said 'I have far more hours than you therefore I MUST be right now go and fly'.
I was fuming
