I was helping my ex with bags and kids to the deptarture lounge, not actually boarding the aircraft. In my pocket was a 1/32 allen key and two tiny little grub screws. I was told I couldnt take them in to the lounge area, I asked the guy to hold them while I helped my ex etc, but he refused, saying if I went inside I had to give them to him and he wasnt allowed to give them back. As they were parts from my work I had to let the ex go, bags, kids and all.
I dont like your chances of getting 200 screws on board.
