You reminded me of something I learned about back when I worked at Disney - most of the bathroom doors on property swing the way you’re complaining about for reasons I can’t remember but might be because you’re supposed to have clean hands when exiting the bathroom (wash your damn hands!). But Disney’s Animal Kingdom is different, because if an animal gets loose the bathrooms are designed to keep animals out, most animals are going to have trouble figuring out how to pull open the door to get into the bathroom. Good to know in case their new batch of cheetahs also figures out how to escape.
