I know that regional accents are part of the rich diversity of our culture, but I do get a bit annoyed when, on TV, you get programmed sub-titles for a contributor from Asia or Africa who is speaking perfectly comprehensible English, whereas we're supposed to understand an interviewee from somewhere in the UK, speaking with a broad, unintelligible dialect, e.g.(but not exclusively) - a Brummie, with no help whatsoever.

I don't want to upset everyone from Birmingham, that was just the latest example of a very broad, difficult to follow, accent.
