Why do many mongolians spit in the streets its fking disgusting

I’ve been noticing for a while now. People of all ages, from the younger generation to the elderly, spitting in the streets like it’s nothing. It’s everywhere, so much so that sometimes it feels more noticeable than regular garbage. And the worst part? If you call someone out on it, they get aggressive. At this point i want the government to fine these mfs with 100k or 200k cause i dont wanna step on ur spits.
