MRT - Disgusting Act!

This happened to me few weeks back. I was taking the train home and this guy sitting next to me was like scratching his head and digging his nose rigorously. What did he do after that?? MAN~~~ he just flicked his fingers to remove whatever dirt collected on his fingers!!!! Aiyo~~~ Damn disgusted man! It was so unbearable that I have to get up from my seat. Ewwww~~~~
