I work at an up/down where military practice approaches are our bread and butter. If I give you an instruction for your climb out, you damn well better comply with it. If you're unclear on what I'm expecting, feel free to ask about it the first time. I'd rather take a second for the extra transmission than have you do something unexpected.
About a year ago, we had pilots start asking about some published departure procedure for one of our parallels when we gave them climb out. Well, it turns out someone published a procedure that none of us were briefed on, made no sense for the operation, and would actually send every departure from that runway across the departure path of the parallel runway. If you fly that instead of complying with my verbal climb out instruction and get into a tangle, you may well get out of trouble when I violate your ass, but you'll surely never get another approach at either of my primary airports when I'm plugged in.
