That is fabulous fighting! But as someone who has experience doing those techniques on the fly against two fighters at once, this isn't usually how it unfolds. At least a couple elements seem carefully choreographed. Are you sure it's spontaneous? (Even choreographed, it would be v. well done.)

I have my doubts — mostly because the diner-assailants don’t look nearly drunk enough

(Not talking about your Dongbei restaurant encounter, of course. Just referencing the video.)
