Nice one, WX Man - reminds me of a similar conversation I had a few years ago with Thames Radar while I was receiving a Flight Information Service as I was routing around their zone. Flying G-FA, I had been told to report at the QE2 bridge and I was just monitoring when I heard:
G-ZZFA: Thames Radar, G-ZZFA, [blah blah]
Thames: G-ZZFA, Flight Information Service you have, use full callsign, similar callsign on frequency
G-ZZFA: Use full callsign, G-FA
Thames: Negative, G-ZZFA, use FULL callsign
G-ZZFA: Use full callsign, G-FA
There was a pause at this point, presumably while the controller found something hard to bash his head against. As I had just reached the QE2 bridge, I called in as requested:
Me: G-BBFA, at the QE2 bridge
Thames: Thank God one of you is awake. Break break. G-ZZFA immediate 180 turn - you have entered the control zone without a clearance. Acknowledge
G-ZZFA: Was that for me or the other FA, G-FA?
Some days the controllers in Thames really do earn brownie points for their patience.
