Why I sometimes don't like people

While waiting for the trolley this afternoon, I found myself standing near two young men and one older gentleman. In the five ish minutes we were waiting, all three of them spat at least twice. Which begs the question, when did it become kosher to spit in public? And not into a trash can, but onto sidewalks and public platforms. No one enjoys the spectacle of watching someone hock a lugie and I'm fairly sure no one wants to step on said mucus so why, oh why, do people spit in public? This is not the wild west - we are not all chewing tobacco and furnishing our living rooms with spitoons; I mean, come on, use a tissue, please?
