We've had gender neutral bathrooms at my job since 2016. Originally, they had male and female stick figures on the door to indicate for both sexes. Well, we have a transgendered woman working there and she complained recently. So they got rid of the stick figures and put up "All Genders".
We have had some issues where some of the guys will pee on the toilet seats and not clean up and lately there has been one of the females getting blood on the floors, toilet seats and not cleaning it up. Oh and every once in a while someone will drop a turd and not flush or not courtesy flush.
