Call of nature, force of habit?

The current office spans two floors, both of which come with attached toilets. In the gents on both floors, there are two urinals - one at regular height and the other at a lower height presumably for accessibility reasons.

Coincidentally, both regular-height urinals have drainage problems; the poor sod that arrives after is usually treated to a nausea-inducing visual (and often odorous) experience. Good thing then that the lower urinals drain quickly.

Incidental observations of timing and residue indicate that certain persons insist on using the regular-height urinals when presented with the choice, despite the unpleasant consequences. And it's not like these persons are of such immense stature that it would require some serious act of contortion on their part to use the lower-height fixture - I mean come on, I'm around six feet tall and I can use it just fine.

Dorks like these should be clamped to the urinal until it drains completely. Along with the jokers that conduct loud mobile conversations while pacing around other people's desks.
