There's an enormous sign in security that says "If in doubt, take it out", as we all know, so that large electronic equipment can be clearly seen on the scanners .
There was also an increasingly angry old guy yelling at everyone at the new security machines to stop taking large electronics out as they were slowing down the new process. The AI also couldn't figure out my laptop was a laptop cos it ended up beneath two books in my enforced rush to chuck everything in one tray as demanded by shouty man.
Of course I got a secondary. The right hand really needs to meet the left hand.....
