Just take a look in the professional aviation part of CHIRP and you will find reams of crass stupidity from the "security" numptys.
The best one recently published was about a ground engineer who was refused access airside because he had two pints of milk for the crewroom tea, he later retuned with four pints of milk and was granted access airside................. the reason is that two pints of milk breaches the 100ML liquid rule but four pints of milk is classed as a "delivery"!
You could not make it up!
