It's a high-end restaurant/night club. Some people want a degree of privacy for whatever reasons. It's common for customers to take short videos of their evening so there is no policy against that.
I'm sure the owner tactfully told the guy thanks for the good effort but knock it off.
I believe he had no clue he was crossing a line, but I won't let it happen again, if it comes to that.
I've been at this place so long I treat it as if I own the joint. Saturday I went to the restroom, and whoever had been there just before me left a horrible smell. I went to the storeroom, got a can of sanitizer/deodorant, and went back and sprayed it! There is always a busboy assigned to service the restrooms, but we were pretty tied up most of the night.
Maybe I'll do my own live feed, but I will have the camera up close showing just me have and proper audio running to it. Then, both of my fans can watch!
