There are even restaurants in London you can't get to without going through a scanner. E.g. half the restaurants at The Shard.

But to give an idea of how idiotic it is: Those are on the 32nd and 33rd floor. Next door is the Shangri La hotel of The Shard, where you can walk straight in and take the lift to the 31st (no scanners), and change to a lift for the 52nd floor (no scanners).
