Imagine a commuter eating a small handful of chips one at a time, mouth open, smacking. "You're chewing loud" names the actual problem: the noise hitting everyone. Replacing it with "you're putting too much food in your mouth" is often factually wrong, and false accusations change the game. My opponent says the new phrase is kinder or more precise, but it's neither when the real issue is sound. In a coordination game, the clearest signal wins: people can fix volume by closing their mouth, not just taking smaller bites. Keep the original.
