Verbal harassment at gas station

I was at the gas station down the street from my apartment in Highland Park when a man pulled up behind me and got out of the car mumbling about Wuhan and Chinese people. He seemed a little manic and unstable so I tried to leave the gas station as soon as I could.

When I turned to glance at him, he had his phone out at chest level as if being covert, seemingly filming me. When we briefly made eye contact he said "f*** you" as he continued to film me. Each time I made full eye contact, he turned his back from me and continued to mumble as if trying to hide that he was filming. I felt unsafe so I got in my car and quickly snapped a picture of his license plate. I really didn't know what else to do. It had me fuming...there's so many Asian American communities in Alhambra and SGV which are neighboring Highland Park - I was thinking about their safety and how this man might've already harassed them.
