I tend to believe Chris Thompson of the two.
I've flown from Popham on and off for years, in a lot of types. I've witnessed several bollockings (thankfully never received any -at Popham anyhow), which were all:-
(a) Delivered on the ground, and
(b) For flying over the Petrol station.
I've seen Chris in action whilst enjoying tea and cake, or flying circuits, and whilst he tends to be a little dour, I've never seen him less than professional in his conduct.
It is however 'injun country around there - and traffic can come from anywhere, and be talking on any or no frequency. Everybody should behave accordingly.
