I'm curious how this works on the other side of the warehouse - in shipping. Especially once you start thinking about the games of tetris that are played when loading the container. Boxes are often not uniform in dimensions or weight, nor should they be loaded like they are in the picture if it can be avoided. They need to be interlocked (assuming non-cubic boxes) so that the entire load doesn't come crashing down if it shifts.
