For all you frequent fliers...think of us poor souls who work airside...EVERY day 3-5 times a day we go through exactly the same as you do...but we aren't anywhere near the plane!!
No butter/jam/frozen food (if it MAY contain a bit of water when unfrozen!) allowed through even to our staff room which is about 20 paces away from the security cone!
However just smile and get on with it...it isn't the security agents fault the DfT change their minds daily!
Belts on 4am...Belts off 6am
Shoes off 4am...shoes on 6am
Keys on RZ pass through scanner 4am...Keys on 7am
I just shrug, smile and get to work...to a MUCH nicer environment then they work in!
