Many people have a hard time using a public restroom, generally because of the public aspect, but unless their fears are justified by disgusting experiences they usually get over their fear in time.
However, if those public potty shy people were ever forced to use one of the 6 Most Terrifying Public Restrooms In The World they’d probably want to refrain from restrooming for the rest of their lives!
Cracked’s classic list includes this one-way glass bathroom/art installation by Monica Bonvicini that lets you feel what it’s like to make in the middle of a crowded sidewalk:
A jaw dropping john on the top floor of the Peninsula Hotel in Hong Kong that'll give folks who are acrophobic and potty shy a heart attack. The wall-to-wall windows in this sky high bathroom used to give the city below quite a show before those grey buckets with backboards were put in to block the view.
And these egg shaped space oddities that lie at the end of a long trek through swanky London eatery sketch, which make patrons feel like they're in a scary sci-fi movie (especially after they've had a few drinks at the bar). These potty pods play creepy music while guests go, making them feel as if they're about to have their internal organs harvested for the restaurant's weekly special!
