People unable to have memories without recording/taking photos

I work at a performing arts center with rehearsal spaces that have windows. During rehearsals we have signs up on the windows saying to please not record or take photos when rehearsals are running (it's plain rude and distracting, and there are people who wouldn't want to be in a stranger's photo or video as they're practicing. We also have kids rehearsing who can't be put online for safety reasons). The amount of grown adults I have to remind to please not record on top of the signs already and get PUSHBACK is crazy (some I have to remind multiple times because they'll try to hide from me). I totally understand wanting to make memories, but not everything has to be documented! Live in the moment! Not every space is open to take photos or record!
