Perhaps I haven't expressed myself very well. By "deal", I mean 'have experienced'. When faced with a new controller all that is required is some human understanding and patience. Occasionally you will get an instruction that doesn't make sense, or some other mistake whilst they get up to speed.
In the vein of the student pilot who muddles up their readback, I believe the course of action is patience, not firing "not good enough" across the radio. I try not to "deal" with anyone at work, if I can help it.
