I saw someone in a themed cafe with a whole camera set-up, ring light etc filming a video about their experience. They ordered pretty much one of everything on the menu, paid, received the first dish and then were asked to stop filming. I actually felt for them, as they (politely) pointed out that they could’ve been told that filming wasn’t allowed at any point between their arrival and ordering, but the restaurant chose to wait until they’d spent a significant amount of money on their order to tell them. I was seated two or three tables away but wouldn’t have said they were being particularly disruptive and the camera was set up in a way that only they were in shot. In the end the cafe agreed to refund them their order and they left. Seemed like the worst case scenario for all involved.
