This was on the news a few days ago. The incident took place in Thailand.
A female Chinese national went around spitting in public areas including public transport. Many people were alarmed at her lack of personal hygiene and possible spread of covid-19 virus. The Thai police came forward to nab her and she attempted to spit on them. One of them covered her mouth and grabbed her by the back. They tested her for covid-19 and thankfully, the outcome returned negative.
Spitting in public is incredibly rude AND disgusting!
