I can't say I like glottal stops and estuarine English either, to the extent where I would certainly offer a job to someone who spoke properly rather than to someone who didn't, all else being equal.
So, in the eyes of the saintly Sweeney Pibroch, I'm probably a terrible snob. And doubly-damned, no doubt, because I use RP.
Oh dear. How sad. Never mind.
