It wasn’t even a good fight. No way anyone was injured by any of the “punches” thrown. Looked like most of the damage was done by the momentum of their own bodies and the ground.
That in mind, I would be pissed if I was sitting with my five year old son in that proximity.
I am not a prude and I know “fights” happen, but time and place, man. Unfortunately, these are people who probably never consider the time and place with any of their behavior.
