It would be worse if you were taking a leak and decided to spit on the floor. Seriously.
Men seem to have no qualms about spitting on the sidewalk while they're casually walking down a street. Women seem to seldom do this, I must add. Perhaps we should count our blessings, as far as the "killing two birds with one stone" attitude that some men show when they are using the toilet or urinal. In my neighborhood, I am constantly looking down whenever I walk on a sidewalk due to the "spit obstacle course" I have to navigate daily.
Men are also notorious for urinating in the shower, but I'm not sure I want to go there! (I do not do this, BTW.)
