Purell for your toilet seat

I collected numerous photos of bathrooms and bathroom signs throughout Asia over the last four years.  (For some reason I find them hilarious and interesting.) Asian toilets range from the pit in rural China to crazy robo-toilets in upscale Tokyo hotels.  Here’s something I’ve never seen before: Purell for toilet seats instead of paper gaskets.  (Seen in the Hong Kong airport.  Wonder if there’s any IP on those units.)
