I don't see that. Looked like she was just going up to the bar to order with him right on her tail, saying things to her, then possibly touching her butt. Watch how she suddenly turns in response to 'something' he does (at 13-14 secs into vid).
The scene starts out with her squeezing by Johnson to get to the bar. She looks over her right shoulder and says something to him. He forcefully squeezes to a spot to her left and there are words. The video shows him grabbing her right arm, pushing her back, and putting his right hand up under her neck. In my opinion she was under assault, and she reacted defensively.

From your description, it sounds like he initiated a physical encounter. I’d think that would make him responsible for what followed.
