Lest we get too focused on this specific scenario, and it is good we do understand what happened and how best to react, we do need to remember the old Zen adage:
Train for nothing so you are prepared for anything.
This does not mean don't train, it means train properly so you can react to the specific situation with which you are faced. If you train for a specific attack, and someone attacks you differently, you are not as prepared to respond - you will respond the way you were trained, not the way you need to react to this specific threat.
Everywhere I go, I evaluate entrances and exits, including emergency only ones, plus who I am with, and what I will do If . . . .
