Usually when I see a single-occupancy restroom it is labeled as unisex and can be used by either gender. But I was in a Starbucks today that had a men’s and women’s, both single-occupancy.
Is there a reason for keeping them separate? It seems like it could potentially benefit men, since there would be less chance of having to wait in line if both stalls were occupied by women. But I think the last time anything was done publicly and specifically to benefit men was about 1875, so that can’t be the reason for it.
