This is "negative marketing" and I would bet money on it being staged. Everything about the way it's filmed and cut screams staged.
The most obvious part is that this dude is laughing and smiling about his five hundred dollar glasses being broken. Come the fuck on this is not natural behaviour, he stands there neatly for the vertical shot by a third party, there's no confrontation, there's no altercation, the rest of the people on the carriage are bewildered rather than behaving like they just saw something go down. Then it cuts to a first person shot of him holding the camera off the train. Fake. Staged for negative marketing.
