ppl like this if they are not nuts its prob bec they want to protest against other mrt passengers for personal travelling space.
this is a wrong thing to do, watever unhappiness is with smrt or go up with sg gov, not take it out on fellow passengers.
same goes for ppl go out littering, dumping without bagging, they think they are getting back at the system when they are really just creating nuisance and making other ppl suffer with them which will not be helping anyone
