Picture a quiet scene in a theater: a phone buzzes, screen lights up, and fifty heads turn. That single glow destroys immersion for everyone, not just the owner. My opponent may call a full ban too harsh, but partial bans fail. Ushers cannot judge intent, and a silenced phone still tempts checking. A clear ban is enforceable: no phone out, no exceptions. The point isn't punishment, it's protecting a shared, fragile experience. If theaters sell silence as the product, they should guarantee it. That is why phones should be banned entirely.

We agree the surgery-call scenario is real, and nobody wants to punish that. But the other side's targeted rules assume ushers can distinguish a dim glance from a bright scroll, in a dark room, in real time. They can't. That ambiguity is exactly why partial bans fail. A full ban sets one clear default, and an emergency can be handled by stepping into the lobby, where a call actually works better anyway. The cost is a small inconvenience; the benefit is a guaranteed quiet room for everyone. Theaters sell immersion, so they should protect it without case-by-case guessing.

My opponent says a total ban is unenforceable because ushers can't inspect pockets. That's a category error: bans aren't meant to be perfectly detected; they set a norm. No-smoking rules aren't enforced in every seat, yet they work because the default is clear. Targeted rules invite exactly the judgment calls that fail in a dark room: was that a watch, a text, a dim glance? A total ban removes that ambiguity. Emergencies still work from the lobby. The point isn't punishing pockets; it's stopping screens from coming out. Clear default beats case-by-case guesswork.
