Barrack lavatory at the Dachu Concentration Camp Memorial Site, DE.
The floor was a holy place. No one was allowed to enter with wooden shoes or even slipper on their feet. Only barefoot or in socks, to protect the floor.. As in the military, cleanliness and tidiness were means of harassment, only here in the camp this was taken to a more diabolical level. "Dachau - a World without God" by Sales Hess.
Not even the smallest spot is allowed to get on the wood, for if the block leader sees it, he will write up a report for punishment right away.. The tableware also has to be completely clean.. You can get an hour of pole hanging if even a single drop of coffee can be seen on a cup. "The Powerful and the Helpless" by Edgar Kupfer-Koberwitz
