Which potty? German perspective
I probably have lost count how many times i've seen women in the sink area of a men's room. There are some bathrooms where, after you pay your 50 cents or 1 Euro, you stand there facing one of two rooms. Both have proper closets - full-length walls and doors - for the toilets and a back room with urinals. Men and women use either - whichever is open.
I've seen Dad's hold their kids off the side of the road so the kid can pee.
So the gender-bathroom thing is pretty silly to me.
EXCEPT. Americans are crazy. Just like the destruction that would happen if the US adopted German traffic laws and regulations - including speed limit policies - (and I suspect the carnage would be worth it eventually), Americans seem more prone to be perverts - maybe it's just the larger sample size?
But that's where the full-size rooms/closets come into play - where the common area is only the sink.
Why don't more american public restrooms have those closets? Because Americans would DESTROY them; have sex in them, do drugs in them, etc, etc, ad nauseam.
“… the greatest detractor from high performance is fear: fear that you are not prepared, fear that you are in over your head, fear that you are not worthy, and ultimately, fear of failure. If you can eliminate that fear—not through arrogance or just wishing difficulties away, but through hard work and preparation—you will put yourself in an incredibly powerful position to take on the challenges you face" - Pete Carroll.
