Postoffices throughout the world have different systems for queuing. These are:

One queue per counter — central queue — ticket/number system

Luckily, the “one queue per counter”-system has been virtually abolished. Nowadays there is a religious-like fight between central queues and ticket/number systems.

Look at a German post-office on a Saturday afternoon. “Central queue” system, waiting time is ~15-20 minutes. All people are bound to the queue. Should anyone leave their spot, the savage mob will make sure that they re-queue at the end.

This robs everyone of the opportunity to use the time in a meaningful manner, go elsewhere during the wait, or to look at all the lovely merchandise on offer. Result: No sale!

The Post´s counterpart in Switzerland uses a number/ticket-system. Result: No monotonous waiting. If the wait is too long, you can make use of that time. Some do whatever, others shop. Conveniently, the post office has a range of stuff on offer. Result: Sales and/or happy customers. Win – win. Should be a no-brainer?!
