You want to try Wallingford Intergalactic Spaceport! Bumbling along on a simple VFR navex which entered their MATZ, but remained clear of their ATZ, I was given 'instructions' which would probably have made LHR's controllers blush.
I then asked for the London QNH, because our destination (White Waltham) was below the London TMA. "YOU SHOULD BE FLYING ON THE QFE!!" came the 'reply'.....
Which was a bit of a surprise - all I'd wanted was some basic aeronautical information and I certainly hadn't said that I intended to change the altimeter setting inside their precious MATZ.
But the top prize for military overcontrol went to Carterton Field several years ago - I'd advised them that I would be passing through the overhead at FL50 climbing FL100 (for high-rot spinning). The top of the Class D CTR is 3500ft amsl, but they tried to control my activity at least 2000 ft above them. So they got mad_jock's "Hey-ho, squawking 7000, QSY en-route" treatment....
I also considered turning off Mode C at the zone boundary, but thought that a bit too childish even for me!
They're much better these days though.
