Plenty of places around the world, squatting over a hole in the ground is the norm. I can see that being an adaptive tool for someone who is new to sitting-style toilets and prefers the old way.
On a job long ago, there was a mysterious series of very unsightly messes left in the rest room. Apparently an intern from overseas, unfamiliar with American plumbing fixtures, tried to use the toilet like a squat by climbing up on top. Hence the resulting mess. The perpetrator was found when one foot slipped and she was hurt in the fall and had to call for help.
The most foul place I've ever been was to an airport rest room (if it could be called that) in Odessa, Ukraine. That's where I first saw such the horrific sight of a poorly maintained squat.
OK, back to the topic... Useless products, right?
