The people in my office building are serious violators of what I believe is the unspoken universal bathroom code: never EVER sit in the stall directly next to an occupied stall unless that is your only option. All of the bathrooms in our building have three stalls. I always take an end stall so that, should someone else come in to the bathroom, they can leave the standard one stall buffer. But, nobody in the building ever observes this standard courtesy and it’s starting to DRIVE ME NUTS. That’s all, thank you.
