Okay, so according to the "instructions" painted on the wall....
... there is no wiping. All contamination of your skin is supposed to be rinsed clean from water being thrown against your skin. No rubbing anything against your skin.
... there is no drying. I guess that's fine if you're wearing a traditional Indian dress and no underwear, but if you're wearing PANTS, don't you want to have a method in place to dry this area that you've just splashed water all over?
I give it two thumbs down. Our system is far superior. (Assuming that there's a working sink with soap nearby, and people actually use it, which may be expecting too much...)
