I do agree there are things the TSA can teach European security agents :
they Euros have a serious lack of attitude ; instead they search my bags and do swaps to check for explosives with fancy electronic devices, something never done to me in the US.

Imagine how much more effecient it'd be, if the Euros learned the bossy demeanor of their US counterparts, patted you down cause you left a coin in your pockets, while ignoring the pile of electronic equipment in your trolley.
