guy recording people in downtown

I was in downtown yesterday evening enjoying some pizza and wine on a patio at a winery. once i start eating this guy walks up and stands right in front of the patio with a standing tripod and camera. After a few mins i confronted him since i was in the frame and felt uncomfortable. I asked him "what are you doing?" and he said he was filming the resturant. He was a fucking creep. He stood right in front of me with the camera on the other side of the patio fence and called me a narcissist because I thought he was recording me and covered my face. I know that he could legally do it but just because something isn't illegal doesn't mean you can be an asshole and inconsiderate. I went inside after that and the employees called the cops lol
