Well to be honest Gem Genie I don't think they're being lazy they more likely want to exclude you, and me and 'the establishment' from their banter. That's the whole divided society, 'excluded sections of' bit, et a. They choose to sound as different to those elements of society they feel as excluded by as they can. No such probs with the presenters though IMO. All speak beautifully in their varied accents.
