Considering it’s actually a private establishment, i think a complaint to the management is justified. On the sidewalk, no, but a business isn’t exactly public. As a previous professional photographer, the absolute assholishness and lack of etiquette is something that is appalling. I always made aware or made to to ask before getting someone in frame for anything other than a candid shot of family if it was going to professionally used. That’s not just courtesy but in a litigious society, essential. But influencers, if I would encounter one, I’d start pretending to livestream and vocally say out loud how i rank their attractiveness (and give low marks) or start doing embarrassing shit like mooning “accidentally” in their background to **** up their shots to make sure others can have a peace of mind to not worry about these idiots. I don’t look good, and would take one for the team gladly if i saw that crap bothering others
