Ultimately, he was more wrong than her for escalating it to violence.
But, she shouldn't have left her cart blocking the aisle and she shouldn't have verbally confronted him for moving it......I mean he had to move her cart to get by, right? She, herself, was being impolite and confrontational.
Then, she had the courage to throw a bottle at him as he was walking away. Well, then I must say, she was asking for a fight.
She can only claim to be half the victim here, I think.
