People cough up and spit phlem on the street, or big snot rocks on the street quite frequently in my experience. China has such a big problem that they've signs saying "please don't spit".
Things are improving greatly in that regard. It's now pretty much the uneducated and the elderly who still insist on spitting. They've been working in the Chinese "countries" (China, Taiwan, Hong Kong, Macau, Singapore) to get them away from the old Chinese TM belief that it was imperative to your health that you spit out phlegm.
In many places "spitting" is now included in a list of no-nos like on the NYC subway, where you'll see signs that say something like "No smoking, spitting, eating, drinking, radio playing" or similar. Remember that in America there were spitoons in pubs/saloons up until the early 20th century.
