I have it marked up with 4 escalation points. She grabs the drink out of his hands. She steps into his space to slap him. He front kicks her. She picks up a weapon.
Ok, here are the ones you missed.
He throws the drink in her face.
He throws her back with enough force to topple over the bench and lose her glasses.
He literally has to take two steps to throat punch her with enough force to throw her several metres back when she is "brandishing a weapon" (after being attacked thrice and not advancing with it).
So it's 3 vs 4 escalation points now even if you grant the more spurious claims you are making here. Like grabbing the drink being violence meriting self-defence. And especially that last attack was entirely unnecessary, the guy was way out of her reach, could have just walked away.
