I mean when you step in shit, you don't just tissue your foot or shoe, you wash it down at the earliest opportunity. Why should it be different for butts?
I’ve first encountered one at a big mall in Thailand (Terminal 21) so it does get a bit of traffic. That was 2012, and as of 2022 they were still there, looking pretty original. They can take a beating.
I added one to the home last year. I’ll never go back to plain paper again.
