Most urinals in India have these - a small wall-ish slab between urinals that start from about knee-height and end at about chest-height.
These are going the way of the dodo now though, for whatever inexplicable reason. (Cost, maybe?)
Lots of places (in the US) have this, but it's ineffective to prevent Awkwardness - they only cover the height of the urinal itself. To fully prevent Awkwardness, I think you need full-height walls, so you can't see your fellow visitor's face.
