Best was in some church I forget the name of in Florida that my college choir sang at. The toilets had plastic covering the seats that would change out if you pushed a button so you'd have a clean seat. It was pretty much amazing.
Worst is probably the one in my ex's apartment that I'm pretty sure he never cleaned.
Best - At that restaurant at the top of the Pilatus in Switzerland, it had funky light projectors that changed the color of the doors when occupied & it was all carved stone, gleaming metal, & glass with automated cleaning features... like using the facilities of the future
Weirdest: the street/park stall put in for an Art Festival, it was made of the 2-way mirror so you could see out
Heroin makes you constipated. The heroin from my last hit is fading away and the suppositories have yet to melt. I am no longer constipated. I fantasize about massive pristine convenience. Brilliant gold taps, virginal white marble, a seat carved from ebony, a cistern full of Chanel No. 5, and a flunky handing me pieces of raw silk toilet roll. But under the circumstances I'll settle for anywhere.
