I think the new your ones may be different slightly, the ones in San Francisco are built by Decot, a french company and the door is swinging I think. If you pull and it doesn't open it's busy. I don't think the french ones have so many buttons, but it's been ten years since I saw one.
Quite a design problem, considering all the variety of pseudo humans that need to be accommodated. They turned out to be a popular spot for various other bodilly fluid doings! <GRIN> Tom
