I was in the men's room in a quick stop on I-15 on my way back from a trip to CA. It was a trough urinal of sorts. In any other setting it would have been a fountain. 4 or 5 guys could stand in an arc, at the edge of the "fountain pool", and make an arc into the pool.
The water flushed down the back wall of the "fountain" just as it would have elsewhere. I've never seen one like that before.
I thought about taking a picture but it was crowded at the time.
