Is anyone still reading?

I just got back from a 7 week vacation. Koreans havent changed. I was at the bus stop and a college kid was there and he:
1.was coughing without covering his mouth.
2. made a loud noise to cough up spit.
3. coughed up the spit.
4. ate a snack without closing his mouth.
5. Smoked at the busstop around others.
I wanted to kill him.
