This could easily be because the top handle is in a more convenient spot so everyone uses it and nobody uses the bottom one, I can’t think of a reason someone would be so inconsiderate as to not wash there hands but so altruistic that they go out of there way to use the inferior objectively worse handle. And human nature would say nobody is going to care about the slightly inconvenient option after it gets boring, don’t believe me? Then why do so many people choose the convenient less boring option of not washing their hands?

The problem with this layout is that the shit from the top handle will drop onto the lower one, thus contaminating it as well.
