Security hall a frustrating, uncomfortable tediuos procedure as is frequently the case at Edinburgh. Poorly designed and laid out. The floored number system at the items for x-ray trays means you often get to share the bad day the person in front of you is having. The distance between you and your valuables is easily the further of any airport. The staff are almost always under intense pressure and struggling to cope with the volume of passengers present. Don't know what the answer is to be fair but may require complete overhaul and redesign of the hall itself
