I was told (by BA ground staff) that internally and informally, the Concorde door is referred to as the 'million pound door', as BA have to pay an extortionate amount to BAA to have that door and not have F class pax walk past the shops.
BAA really is the pits and the economies they make on T5 are silly. No paper towels in toilets - does it never occur to these dimwits that people may want to wash their face? Lack of moving walkways on arrival - one can go on and on. Public flogging and execution of the top three levels of BAA management would be a good start - 'pour encourager les autres'.
