The term affirmative may have been heard as negative, so that's one thing that always stuck. Also remember that ICAO numbers stop at 9(in terms of enunciation), therefore I always enunciate altitudes such as 17,500 as (wun-seh-ven thousand fife hundred). Of course that seems not to apply to actual flight numbers and I've yet to research the 'official' ICAO phraseology for flight numbers. eg. I always hear 2263 as twenty- two sixty-three in the US whereas in International airspace for the most part it's enunciated as too-too-six-tree.

All in all I join in for standard phraseology at all times but also see nothing wrong with tasteful greetings/salutations.
