I'm affaid I am guilty of this, but only when I'm struggling to get my 2 year old to eat, I never have the volume loud though. CBeebies on iPlayer is a lifesaver

I always proclaim loudly “oh, I didn’t know they were filming the Apprentice around here” and stare at them. Morons.Also, people having phone conversations on public transport on speakerphone.
