While this has nothing directly to do with the OP, but there's an assumption of cleanliness amongst everyone I know. If it looks clean, it must be clean, right?

While this has nothing directly to do with the OP, but there's an assumption of cleanliness amongst everyone I know. If it looks clean, it must be clean, right? 100% completely wrong. Simple casual observation of people exiting restrooms is proof that if anything is touched, it cannot be clean. I have seen far too many people not washing after going #2 that I simply do not trust a single damn thing that I touch in public. I'm not OCD, but the general piggishness of a large portion of the population is quite disgusting. I operate on the assumption of filth, and it has kept me from getting sick for nearly 7 years. I avoid public restrooms unless nature is screaming at me, and I carry safety wipes and use them all the time. I use them the moment when I get into my car from visiting anything, anywhere. I filled in for the building manager at a higher end office building, and the things I have seen were shocking. I have seen non-public bathrooms defiled in disgusting ways...all on touch surfaces. Feces, blood, ejaculate, and who knows what type of drippy bile. This in an upscale business building, mind you. Imagine what horrors are visited upon your common public restroom. I even wash my soda cans. Probably a bit overkill, and my dad used to give me stick about it until he got sick from drinking from a can that had mouse pee on it. The neat thing is that being fastidious doesn't take much time or effort. And, it's not like my immune system became Superman overnight 7 years ago, it's that I started being careful with what I did with my hands.
