Germany is famous for its Oktoberfest.

Oktoberfest is a big festival where people are basically sitting in big party tents the whole day, trying to eat & drink as much as they can (like it or not – it is what it is).

Traditional german music – which is being performed within these tents – makes the people feel like having to drink even more.
In order to deliver all these drinks and all the food to the tables within the tents you need a team of strong waiters & waitresses.
And in order to make most of their time you need an efficient organization. If you ever had the chance to observe the scenery within these party tents you might have noticed that the waiters are usually not taking any step with empty hands. A typical scenario might look like this.

The waiter carries full mugs from the bar to table X. Having placed the full mugs he takes the empty ones – if available – and brings them back to the bar.

Again, he picks up full mugs and carries them to table Y.

Table Y has no empty mugs – the guests have just arrived – but our waiter is passing table Z where lots of empty mugs are waiting to be picked up.

Sidenote – The world record for carrying these traditional 1 liter mugs is held by a guy called Strümpfel. Last year he carried 29 of those mugs at a time for 40 meters.
