I don't get this; this happened at my workplace too, until we installed a coded lock on the restroom (which was otherwise accessible to anyone in the building). What kind of boor has a professional job but can't piss in a foot-diameter hole and is too lazy to clean up when he does so?
Please don't ban my account, that's true and anecdotal - 75%+ of my coworkers in that department were Indian so maybe it was just the odds.
No reasonable idea of civility (https://news.ycombinator.com/newsguidelines.html) would include "anecdotes" about the grossness of other races' or nations' bathroom habits. I'm flummoxed that this became necessary to state explicitly, but I guess everything happens if you moderate an internet forum long enough.
