Is it not a bit weird sometimes, for example when the 3 employees became Cybermen and had 2 bluetooh thingies on their ears, nobody seemed to notice until it was too late..i mean HELLOOOO common sense! and nobody ever asked who was the man holding the olympic torch in the episode "Fear Her" (he was the doctor, but nobody cared..) and finally, is it not a bit too earthbound???
thankfully i know no-one who wears one of those ridiculous 'ooh look at me,aint i cool' headsets but if i did and he wore two of them i wouldnt think he was being controlled by an alien master-race !
