Not as subtil as I saw in the men's toilets at the Singapore airport where bang on the middle lower part of "my" urinal was, what I thought to be....a fly! but the fly was not moving
I looked at the urinals next to "mine" and there they were! Someone had thought about helping men to aim better by puting an image of a fly, LOL! Very nice little "touch" I thought. But this one is "bang on" on your face, hope lots of people can read English
