OK I'll bite.
If by "acceptable standard of RT" you actually mean "Call the most appropriate ATC Unit". I am sure that, given a position 30 miles west, the guys at Southend would have suggested Le Touquet man call someone more suitable such as Farnborough Radar (East), Biggin Hill or London Information. Or maybe the Pilot had heard about the Zone transit and conflict avoidance "service" (see my previous post) and decided to stay "well clear"!
