My daughter visited a supposedly ladies restroom in California recently. She came out of there very disgusted due to the filth in every stall. Urine all over one toilet seat. Fecal splatter on another. Fecal and blood splatter in another and so on. She vowed that her time in that state would be short lived. And that she would homeschool.
I learned to go 8 hours without using the bathroom when I was in high school. It drives my family crazy on long car trips.
