<<Anyone complains to me about ATC, I say there isn't a problem and if you were refused entry then, there was a reason for it. >>
Good on you.... if lots more pilots would only understand that simple fact life would be much easier! In my reasonably long career in ATC I experienced far more problems caused by light aircraft than I ever did with the big jets. However, I always did my utmost to provide the same service to all, and I know that goes for my ex-colleagues too.
