I've just had an argument with someone in a cafe who took umbrage to me politely asking them to turn down the volume on a video they were watching with their whole group on full volume. Apparently, I'm rude for asking them to turn it down. Is this socially acceptable now? It's driving me mad- everywhere I go, people are incapable of using headphones and subject everyone else to their noise. I find I have zero tolerance for it and give a death stare until they get the message. So AIBU? Is this the norm now or are these people just selfish inconsiderate arses?
