I love it when the ramp doesn't advise me that the headset is busted, and that they're going to be using hand signals. I usually find out when they give me the release brakes hand signal, and I shake my head no. Eventually I yell down to them through my window that if we're going to use hand signals that my FOM requires them to put the gate back on and give the ramp crew a face to face briefing. Magically, a working headset normally shows up 30 seconds later.
Always.
Yet I get memo after memo about D-10, D-5 and "…the tug driver SHALL", which is great, but in reality…
