The most amazing security process I've seen was AUH (Abu Dhabi). What a joke! Beep through the metal detector? Ehhh whatever. Don't have a passport? Ughhh just go. You'd put your bags on the X-Ray conveyor and no one is even sitting at the screen to watch what's in those bags (he went to get coffee).

Luckily I'm the worry-free guy that I am and just thought it was funny. But when I think of the fact that you don't have to go through security in places like LHR and someone could board a plane with a weapon in AUH and end up on a flight from LHR to JFK...
