I never, if I can help it... and most times I can... flush a public toilet with my hands. It's not beyond me to lift my leg just about clear over my head so that I can push down on the handle with my fully covered shoed foot.
Is this strange?
It's just that the thought of the possibility of getting some stranger's number one or number two on my hands from them making a mess when they wiped and then getting it on the handle... well really it grosses me out!
So I foot flush. I am a foot flusher. Self proclaimed. And proud of it!
Now... if I ever wake up in the middle of the night, after sleepwalking down to the boot closet, nawing on that same foot flushing pair of shoes because I thought that in my sleep it was a yummy chicken salad sandwich or something that might change how I flush entirely.
