So the last shall be first...
A group of Danish researchers have found that queues move faster if people are served from the back.
A new paper by Professor Lars Peter Østerdal and assistant professor Trine Tornøe Platz from the department of business and economics at the University of Southern Denmark claims that by serving the last person to arrive first in a queue, waiting times are lowered.
Orderly queuers rush and form a queue to be served and latecomers who hate queueing trickle in afterwards. But they wouldn’t do this if the last to arrive were served first, researchers found.
When the last person in the queue is served first, not everyone can arrive at the last minute. This motivates people to arrive early, or to arrive in a steady stream.
