Have you ever been to a movie theater in Viet Nam ( I can't speak for the rest of SEA )? It's incredibly common for people to talk to each other in a full theater and use their phones (at high brightnesses). I suspect it's because not much care is given to being able to hear the dialogue in the movie since everyone is reading the subtitles anyways. Complete culture shock compared to the US.
