When I was in my late teens, I worked maintenance at a local truck stop to pay for school. The comment about the women's bathroom being worse? That's generally accurate (some truckers are the exception, like the guy pooping out a 4"+ diameter salami turd that plugged the toilet and had to be broken up with a plunger or the guy who ringed the stall with epoxy runs/explosive diarrhoea) due to the "other" products that are dealt with in their washroom. And women can be GROSS! You find feminine hygiene products in the toilet tanks, or stuck to the stall walls, it was not fun.
Ever since having c-diff, I've have a sensitive stomach. Certain things don't agree with me and sometimes that's a surprise. I absolutely abhor pooping in a shared space and will only do it if I'm absolutely desperate. If I can find a private bathroom where people aren't going to be hammering on the door, I'm fine. This means typically when I'm on the road, I'll eat stuff I know I'm compatible with (no experimenting). I actually have a fair bit of food anxiety from this, as restaurants tend to have shared bathrooms. Often, if I'm travelling, I'll order takeout instead of sit down and then eat it in my hotel room. Even though like 90% of the time it's fine, it's a major stressor for me now (I used to have an iron stomach, could eat absolutely ANYTHING!). It sucks, because that means I generally avoid dinners out with my coworkers.
On the other hand, I'll pee almost anywhere, that doesn't bother me in the least. If you gotta go, you gotta go.
I try to find a cowl to pee in, usually a car that is parked in a way I don't approve of.
