Whilst doing my PPL and since, I spent a lot of time flying around Shawbury and would always contact them. I have found the controllers there most helpful and their unfailing patience and politeness with some people has never ceased to amaze me. I always felt somebody was looking out for me. (Don't worry, I still maintained my usual lookout). It was in complete contrast with a civil airfield not too far away whose controllers' reputation for their attitude towards small GA was, to put it mildly, anti-GA, and on one occasion involving myself, resulted in a phone call of the tea-no-biscuits type by the CFI. The CFI had been sitting next to me and there was nearly a CFI-shaped dent in the roof of the poor little C152.
