Or will you just get angry with the nearest official? Professor Richard Larson, an electrical engineer at the Massachusetts Institute of Technology, hates queuing but rather than tear his hair out, he decided to study the cites an experiment at Houston airport where passengers had to walk for one minute from the plane to the baggage reclaim and then wait a further seven minutes to collect their were frequent, especially from those who had spent seven minutes watching passengers with just hand baggage get out airport authorities decided to lengthen the walk from the aircraft, so that instead of a oneminute fast walk, the passengers spent six minutes walking 47 The extra walk extended the delay by five minutes for those carrying only hand baggage, but passenger plaints dropped almost to reason? Larson suggests that it all has to do with what he calls “social justice”.If people see others taking a short cut, they will find the wait Another aspect Larson studied was the observation that people get more fed up if they are not told what is going But even knowing how long we have to wait isn39。s roundhouse?
