I can't believe how many people do this in public! This is so gross and unsanitary! They just casually spit in public on the pavement, on the sidewalks, just about anywhere outdoors. Not only that, but most of their spits are phlegm-spits, which is even more unsanitary and exposes the public to whatever crap they have inside them. Who wants to wait in line outside a restaurant only to notice someone's green/yellow/white phlegm sitting on a nice green leaf two feet away? GROSS! How hard is it to use a paper tissue or a napkin or something like that and throw it in a trash-can? How difficult is that? Barbarians!!! And what's even worse some of these people would complain if someone farts or burbs!
