I agree that some people might find the CFI on first encounter a bit loud and maybe even rude, but once you meet him a few times you find he is actually a pretty nice guy that just wants the best for his members and instructors.
Living nearby Panshanger was the obvious choice when I wanted to do my IMC. My enquiry in the clubhouse was met with unforgivable rudeness by said CFI. I was extremely embarrassed by him in front of a number of instructors and students etc. I never got to meet him a few times so assume he is not a nice guy - I have never been back. Did rating elsewhere and very satisfied.
