Or maybe they just just don't care
I was on a bus earlier. Front seat at the top, so I was 'driving' (very exciting!)
A lady got on and sat directly behind me. She took out her phone and made a call. Her opening words were "I'm on a bus so I can talk to you properly"
She then spent 30 minutes talking about work. Work she'd done, how much she was going to claim (£250 per job but she wanted £400), what to say to 'them' to get them to pay her the £400, acknowledging that she wouldn't get the £400, and on, and on, and ON!
All at high volume. Such high volume that at times it actually hurt to only be two feet in front of her.
Being a typical English wimp I obviously didn't say a word to her. But I was thinking, lots of people have loud conversations on the bus, train, wherever. It doesn't seem to worry them at all. Do they not realise just how very very loud they are?
Obviously I could have moved but I was driving the bus!!
