See through toilet

Yes, there is a restaurant chain here that sells mainly sandwiches. You can’t see anything from the outside, but once you go in the bathroom you see everything going on outside the bathroom. I’ve been there several times, and have used their bathroom, probably twice. It didn’t bother me.

I have particularly bad luck when it comes to a lot of things, and thus, I am CERTAIN that some of that bad luck would kick in while taking a crap in one of these and the opaque glass malfunctions and I'm left literally caught with my pants down. lol

It's a shame that YT link isn't working. But hey, I’ve seen similar videos—or maybe the exact same one—you shared here. Honestly, I wouldn’t feel comfortable spotting them outside either. Sure, they’re not actually watching you, but the moment you see them, it’s like some weird reverse psychology kicks in and suddenly you feel like you’re being watched too. It’s a bizarre game of “I see you, so now you see me,” despite all logic saying otherwise!

I have seen toilets with transparent walls in Paris. I would not be comfortable sitting inside.

It wouldn't bother me

There is a five-star hotel here which has such a toilet on the top floor. You can see beautiful sea view from the toilet. But I wonder who cares to enjoy the view while using the toilet.
