You haven't been to an American movie theater. If @buckytom and I were sitting next to each other, I couldn't hear him eat that combination he described.At the stadium to see a football match, or to watch a basketball game, or to attend a sports event anyway, obviously the thing is very different. I take snacks myself, it's normal. Everyone shouts and encourages the team, it is a normal situation. But in a theatre no. I'll eat my nails at least! It's true that there is Dolby Sorround in the cinema that combs your hair, but when you have someone who eats chips right next to you or in front of you, you hear it.
