I would like to start a new campaign for mixed lavatory etiquette.
All people including those with penises must sit down on the toilet, standing up is forbidden. The seat must remain down.
All people including those with penises must shut the lavatory door.
Workplaces should develop policies, linked to disciplinary procedure. Anyone caught violating the protocols will get a warning, third strike and you are sacked. Whoever you are.
I can’t see any non-penis people complaining.
There you go.
