Extreme vigilance is advised
As far as I know, there is no such thing as a one-size-fits-all airline security method. For many passengers, it’s no longer necessary to pay attention to their steward as he goes through his routine for the sixth time that day, believing he knows it by heart from years of flight experience.
It’s also possible that this person has never paid attention to anything. Neither a flying technique that is fully fun nor an appropriate explanation for what is happening exist.
