I used to work in a warehouse where the restroom had a long "gang" stainless steel sink in the men's room....drivers often used it to take a leak because it could honestly be mistaken as a trough urinal by the line drivers who'd be making pickups or deliveries.

Finally, some signage halfway cured the problem.

One place I worked had a large half circle sink in the men’s room. I walked in there one day and a visitor was taking a leak in it.
