I don't mind "coaching" an newbie on airplane specific characteristics or procedures and airline specific operations. I should not have to coach basic IFR or radio procedures or IAS vs TAS vs GS or basic aerodynamics like this....

FO..."Ground Flagship 5900"
ground..."go ahead"
FO....."flagship 5900 holding short of papa"
ground..."flagship 5900 what gate are you going to?"
FO......."A3"
ground...."flagship 5900 taxi via papa mike mike6 to the gate"
fo.....'uhhhh...roger" (even though i have no clue what the route is)

at this point in the career, do I really need to tell them to turn those 6 or more sentences into 2 by using the basic who you are, where you are, and what you want to do primary radio etiquette?
