Pay attention to signs! That giant "W" on the right? It's for the water fountains. That's actually the men's side of the restrooms, women are on the left. Nearly everyone was going to the wrong side.
@dillotest0 They aren't being disregarded! A giant W like that is a pretty nation-wide symbol for women's, especially when it's right on a bathroom wall. If they put it in the middle, over the actual fountains, it wouldn't be such an issue. The actual bathroom signs are small, and when the only difference on those is the two little skirt corners on the woman (or lack of skirt corners), they're not going to jump out at you when you're sure you're already going to the right one.
