So what if you only have auto toilets in every stall at work? What do you do then? What do you do if these things self trigger and you are shocked with a cold blast where the sun don't shine. I can't be sitting there enjoying Shaugnessy rag on the sox when I'm getting my ass super soaked...
So i take a piece of toilet paper and cover the little infrared (the black glass) on the module where you normally would have the lever to kick on. It's the best because it's still hygienic since all you have to do is throw the paper into the toilet after and the module still flushes, and your ass don't get the rinse cycle that it probably deserves :-P

Moral: Wrap it up...
Keep dancin'
