Nope!
You cant tell people what to do.
I’ve paid for the cinema ticket and if that means I’m gonna be eating popcorn THAT THEY SELL IN THE LOBBY or i may open my mouth to talk WHICH IS HOW MY MOUTH FUNCTIONS, that’s my deal. It’s not up to anyone to police strangers.
Can’t stand superior cinema toss pots if i’m honest! Stay home if other people bother you so much.
