As SLF scum I prefer an exit-row seat and thus have heard a bag of 'briefings'. Almost all are two steps: "Tell me you're willing and able" and "Look at the pretty pictures on the safety card". Exactly 1.0 times an FA took a moment to explain how to operate the door. I'm pretty sure that was a European carrier. Here in the colonies we don't want to even briefly entertain thoughts that accidents do happen.
I doubt that most amateur door-sitters even realize that there will come a very persuasive "Evacuate! Evacuate!" call when the moment arrives.
