Exactly. I would expect it not to bother anyone on a busy street, but I would expect to told to stop it in a library, and to be kicked out in a theatre.
Phones on silent in a theatre yet with a sea of bright silent phone screens surrounding you as people watch TikTok, text, etc., the movie won't be very entertaining. Why I stopped going to movie theatres about 10 years ago.
I meant a theatre as in stage, not cinema. Rare for phones to be used even on silent in my experience.
Now is your time. Everyone else stopped going to the movies 10 years ago too!
