The bathrooms at the Parque Ecológico main building dont have toilet paper in the stalls. Instead, you must take toilet paper from a large dispenser located at the entrance of the bathroom. While this makes maintenance easier than having it in every stall, I wonder how such a thing would be met in the US.
I can see that such a practice could diminish the amount of toilet paper one might take, since there might be a shaming factor involved. "Why is that guy taking so much toilet paper?" would be what a person would think others might be thinking of his removal of yards of toilet paper.
Of course, it would take time to get used to, and there will be many angry and embarrassed people stuck in stalls.
