At first glance I would have said that the guy is 100% at fault, but after watching the interview she was standing in the middle of the escalator (instead of standing on the right to allow people to pass, like civilized people) yet she felt the need to throw some sass when someone predictably brushed by her trying to walk past. She's an asshole. She probably spends all day doing shit like this, then wonders to her friends "Why is drama always finding me?" Bitch, you're the drama. The guy is still at fault for snapping and doing that though; that's not normal. You're not going to last long in civilized society if that amount of frustration is sufficient to make you go violent. Just tell the bitch to stop standing in the middle of the way.
