He could/should have popped her square in the mouth after saying something like "You have robbed me of my property. Return it immediately or I will use fore to retrieve it." Then done so.
He also should have performed a citizen's arrest and had her prosecuted for strong arm robbery.

The way it ended now, I wouldn't be surprised it she just went out and did it again. Like a small child, she had the look of someone who
voluntarily gave up the hat, but knew she was still in control of the situation, what with that stupid smirk on her face.
I would have laid her out, and told her this is what equality looks like.
