Yes - pubs often have the TV on silent and if it's BBC or Sky news there's live subtitles with howlers every few words. They irk me so much I can't concentrate on anything else. It's like a car crash, I tell you.
The attempts at spelling 'Machynlleth' during that recent tragedy with that poor little girl who was kidnapped were fascinating (as are most subtitles when anything that's not plain English is involved).
I remember someone complaining to Points of View that Helensburgh had been subtitled Helen's bra.
Some days I get so irritated that I have to turn them off. The One Show seems to be bad for it. Then they spend so long trying to repair the damage that they cut out a section of speech. I'm often trying to figure out what someone said but can't because they cut them out.
If you're ever in the mood for a laugh, stick the subtitles on during the news and see what they come up with. I wish they'd all do what 5 do and pre-record them.
