Walkthrough Shoping Centres (Formerly known as Departure lounges)
It seems in the Uk it's now obligatory to have to walk through a winding shopping mall to get to the (increasingly reduced in numbers*) seats in departures. Stansted is by far the worst, but others are gaining quickly. Maybe it's just me, but I would consider paying a small fee for a 'fast track'!
*I'm quite sure the reduced seating is to encourage you to spend money in the various outlets.
