"I hope the glass toilets were also opaque!"
Ha ha! Got me! No, I meant those were the things that *were* opaque, or at least not transparent. (Frosted glass isn't *opaque* - light gets through it easily - but there's no way I'd call it transparent.)
And I have seen a place with toilets that had glass doors on the stalls.
In front of the big art museum in the middle of Amsterdam there is a restaurant called "Cobra". It's named after the art movement(1), not the snake, and isn't at all dodgy. In the basement, there are large and posh toilets, and as you arrive, there is usually a mix of opaque and transparent glass doors on the stalls. And you notice that ALL the opaque ones are taken, and ALL the transparent ones are free.
But nature continues to call, so you go into one of the available ones, hoping that there are no voyeurs in the area, and you discover that as soon as you lock the door, the glass becomes opaque.(2)
But before that moment, the urge to stick a cork in the orifice and run screaming for your hotel is very strong.
(1) COpenhangen BRussells, Amsterdam, if you must know.
(2) Well, in 2006 it was like that.
