you lightened up my mood
at the same time, I have to say I've never personally met an unreasonable security guard, those I met all seem to do an effort to make individual decisions despite silly rules, and I got to keep knives, toy gun, and cough syrup ("because it's christmas", absolutely lovely, no sarcasm), I discarded numerous water bottles, yoghurt, some nail clippers and one particularly expensive shower gel without hard feelings, and when I very rarely get the pat down treatment, they look apologetically at me and say "not your fault, it's the random beep", and I worry about the discomfort for that person. Heathrow is a particular headache though.
