I agree with Vector and HD on this. There are so many different ways in which an ATCO will do something – 20 controllers will handle a complex busy situation probably 20 different ways and they have to keep changing their plan since the traffic situation is constantly changing. Standard phraseology cannot be used for every situation, particularly on Aerodrome Control, therefore controllers will slightly modify their words as necessary.
However I do think that far too few pilots understand the way ATC goes on. At my unit as part of the Unit Training Plan a new controller has to spend some time with the flying schools in order to get a some knowledge of how they operate/what they like/don't like etc. We hardly ever get student pilots visiting radar or the tower to see it from our side.
