At work there were a few times when an older lady who worked in facilities/janitorial would come into the washroom when I was at the urinal. I was facing the other way so it was no big deal but I thought it was funny.

For the women's washroom the cleaners are required to shout Facilities! a few times before entering. It's odd though because women are in stalls and men are skin to the wind at urinals. But I do find US and Canada are becoming incredibly prudish. I've read even gyms are installing individual showers/rooms since the new generation don't like to be seen naked.

Even scents are illegal or not PC "this is a scent free workplace" signs are ubiquitous. But people in other countries laugh at how ridiculous that is.
