My Dparents (late 80s) have to have all phonecalls on speakerphone, but that's so that my DM (dementia) can hear what's going on, or my DDad gets the 3rd degree as to what's being said. This I understand.
Why though, do loads of people have phone calls (not videocalls) on speakerphone instead of at the handset? In the last 2 weeks, I've been close to people almost shouting at their phone, all the way round the supermarket, sitting at a cafe, and on a train, with their entire conversations broadcasted?
Am I missing something?
