I was with my wife (now ex) saying goodbye at YBCG, the kids wanted to wave goodbye to mummy from the dept lounge. I was stopped at security with 2 tiny little machine screws in my pocket. They were from my work and were needed but I was not allowed to take them in to the dept area, even tho I wasnt flying. The guy wouldnt even hold on to them for me so I could collect them on my way out. He said they could be bomb parts!
