Everyone is just too obsessed with procedures and getting it right by the book when really it is all about communicating in a professional manner.
Mate, we get checked 6 monthly plus a contextual report (attitude, yearly). We also get random voice sampled, which can (and has been found to) be embarrassing!
As Leadsled says (good lord! Taking a good, long, hard look at myself) If it's learnt correctly from the start it'll be done properly. The school at Mangalore that does international students (Asian) obviously teach the students the correct calls...........because they are correct.............right from the start. I have not heard one of them utter
'Request traffic and code' when they are given IFR traffic they don't read all the superfluous garbage back, just their callsign.
