One day, senior management decided to start replacing flush urinals with waterless urinals. You know... save water, save money and help the environment. Problem: The kooks who invented waterless urinals didn't understand that part of urine is an adhesive gel. When somebody pisses all over the backsplash, a lot that gel won't go anywhere near the drain unless there is water to dissolve it. The result was that there was always a very strong odor of stale urine in the restroom, even when it was cleaned every twenty minutes. It only takes one person using the urinal to add a new coat of gel.
Management was not pleased, after several weeks of that. But, instead of looking at it with any measurable degree of logic, they decided to blame it in "slacking".
Some people around this casino don't enjoy taking the heat for management blunders.
So, one day I showed up for work and the department head was talking about how a "vandal" had wrecked a urinal.
It was replaced with a true flush urinal. End of problem.
I still don't know who the vandal was.
