All public bathroom doors should exit outwards. I should exit by pushing on the door. I do not want to exit but pulling on a handle or knob which is covered with germs from the hundreds of people who left before who didn't wash their hands. (BTB, simply running some water on your hand(s) for two seconds does not do anything. Use soap. Warm water. Lather. Rinse)

I am aware that some doors cannot open into places with heavy traffic, but more thought should be given to this idea during the design.
