I've started to notice that when I sit on the facilities I always sit slightly off center... if you drew a line directly forward at a right angle to the tank, I find myself subconsciously sitting a few degrees to the right. In fact I've given a name to when it happens, I call it "slicing the pie" because I imagine the angle created as an invisible slice of pie. Next time you're on the bog try to make a note of your angle, I think you'll be surprised it's not actually 0 degrees.
