Queues

Well ok of course I hate queues – who doesn’t?
But I have spent a lot of time travelling recently, and I particularly hate airport security queues (I hit a record at Dulles Airport, Washington recently at 90 mins – passport control itself only took 2 mins!!).
Generally I can cope (although no-one needs that when your body thinks it’s 2am) but I was particularly bothered for people who weren’t deemed as most in need of help but certainly couldn’t deal with that sort of queue.
Surely there is a way we could introduce some sort of ticketing system to allow people to sit and wait their turn?
A prime candidate for service design. Thoughts gratefully received so I can pass them on via sites like http://blog.tsa.gov
