If there are shit smears, I feel it is my duty to hydro pump them off.
Even if they are under the water at the bottom I can get them with enough force.
Normally I just aim for the water, it alerts people to your presence. When in public toilets:
Personal urinals: I aim for the hole. Spraying on the side/front just sends it right back at you.
Them long ones which stretch along the floor: Straight down normally. Unless I'm where the hole is, then I slam it in and watch the bubbles rise.
Yes. We need more people with locations like yours.
