I fundamentally disagree. I have multiple experiences of iPad + laptop on top of each other gets pulled to secondary scan. Or my cords bag (I don't carry many) having questions. As a result, I always take everything out into multiple bins. They get annoyed at the start, but it goes through the machine faster
My sense is security company KPI's are based on how fast someone goes through the body scanner, not how quickly they depart with all their belongings at the end. SYD int'l had 3 people getting people through body scanners (so no wait). but only 1 poor soul doing the secondary review... which was up to 8 trays before a polite discussion with a team leader asking him "what do you see - where is the bottleneck" adjusted the staffing configuration
