This was to eliminate smoking in the bathrooms.
It did, and nobody used them.
We just smoked outside the back of the building.
I don't care if someone smokes, as long as I don't have to inhale the smoke. A lot of campaigns against smoking in public places, from school until today, made life unpleasant and dangerous for people like me: smoke filled the few remaining non-enforced places, from bathrooms to elevators to airport exits. Turns out there's correlation between "smoking ban not enforced" and "I can't avoid going there". Whenever they instead end up with smokers gathering in the corner of the street I can just go around: that's great, hope that no one disturbs smoking in that corner as long as possible!
In the old part of the buildings, we still had proper stalls, some even with a small sink inside the stall.
