Except of course when they have people 'guiding' you to the correct queue.Reminds me the security check scene from 'Up In The Air', so funny
Its all about choosing the right queue...
I too stand laptop/liquids bag ready, and wear slip-on shoes when travelling. All my loose bits n pieces (phone/wallet etc) are either in a jacket or bag pocket ready to extract back onto my person as soon as i've been through security. I'm still tweaking my method, but I have it down to a pretty decent art now.
