In a paper titled "The curse of the first-in-first-out queue discipline", economists Trine Tornoe Platz and Lars Peter Osterdal argue that the best method of serving a queue is to serve the last person first.

This is because having the first-in-first-out system encourages people to join the queue early, causing a backlog of people and increasing everyone's waiting time.

Seriously? Just use QueueTix app ( to manage the queue and join the queue!
