Dave,
I really can't believe that you've gotten so wound up about this. The difference is so small.
Your way, which is correct in the UK only
Made up twr, Gxxx request traffic service
Gxxx, made up twr pass your message
Made up twr, Gxxx <message>
The ICAO way, which is correct everywhere else
Made up twr, Gxxx
Gxxx, made up twr pass your message
Made up twr, Gxxx <message> flight information service
The difference is so small that noone should be getting too upset about it.
But since you're getting so upset about people using the incorrect phrasology in the UK, do you follow the correct phrasology when outside the UK, or do you stick to UK phrasology when abroad even though it's incorrect?
