Plumbers always have the best restaurant recommendations
Whenever I use the security lane at an airport, I enjoy watching people retrieving their bags and metallic items when they emerge from the X-ray machine. You can quickly divide the population into two: a small minority of ‘logistically aware’ systems-thinkers and the logistically challenged majority. To anyone with a grasp of systems thinking, it is obvious that the throughput of a security line is reduced when only a few people can retrieve their belongings at once. People who self-importantly collect their stuff as soon as it exits the scanner are slowing the queue by 70 per cent or more.
