Ala Moana Mall- WTF

At mall, a man hit me hard above my bicep as I was getting on the escalator after parooIng the North Face store. Not sure if he was trying to punch my face. I reacted and told him not to hit me...he said sorry. Asian guy with Aloha shirt, cap, big sunglasses and light skin with some moles. 

I don't recognise him...went to mall after email from my father.
