"I was surprised to see just one unisex bathroom with about six private stalls and a communal sink area...and a sign above the toilet, showing a stick man tinkling into a toilet with a line through it" noted the patron. Where are the signs demanding lids be lifted - do they expect men to be courteous too?
The aim is to prevent men from peeing on the toilet seats, presumably. A practice apparently often done by the cruder members of the knuckle-dragging gender. No argument there, but how do you catch them?
Even urinal peeing present challenges as men often, in some odd ritual, dim-sightedness, or territory marking make a mess even at home. Some men miss the urinals entirely, spraying the walls, floors; sometimes even reaching the operating handles and nearby sinks.
