It doesn’t make sense to have a bathroom that only has 1 toilet to be only used by male or female. If someone needs to go they need to go and since only one person can use the commode in a bathroom like that, why keep the mens and womens facility separate. Just have the bathroom as gender neutral for whoever needs to go. I understand for bigger restrooms that have multiple urinals or toilet bowls sure, keep them separate if you want. Although I know there have been cases where the lines are just way too long and people need to go and I remember hearing about some lady getting in trouble for using the guys restroom.
