Phones are generally banned for any theater shows, broadway shows, symphonies, operas and the like. Case in point, I was at the Salzburg Music Festival last week for a symphony and we couldn’t have phones out once the performance began. Saw Hamilton in Chicago a few months ago and same thing. Phones allowed during either performance would have ruined them.That begs a question. I wonder how operas, theater shows (like cats)treat phones. Are they allowed? I know some concerts make you use yonder.
Though bootlegs of stuff like that do, of course, pop up occasionally. That’s why bootleg copies of movies do too. There’s always gotta be someone to violate the rules.
