What you jolly fine ATCO chaps forget is that whilst you're ALWAYS esconced in your own little radar room or tower, WE are in an ever changing environment that (believe it or not) has different rules, regs and PHRASOLOGIES!!!!!!.
I do agree that there is some awful radio work from some pilots - it makes me cringe to hear it sometimes


But have you thought that when you just get something like "affirm" in response to an "are you ready" maybe the guys in the front are busy with something and only vaguely heard what you said. Yes, I know we're supposed to maintain an ear out - but that doesn't always happen... Tiredness, tech problem, cabin problem - I could go on!!!
And as HS points out - any R/T calls whilst we're landing will be ignored
