Everytime boarding to subtrain in Seoul, we can meet mannerless oldmen. They are seems to mostely thinking 'I'm special' or loyal. Maybe they are lived in long time and because of this, They may think like - I can void younger people, public morality even public enforcement.
We don't need to hate that rude oldmen, but as their conduct, they will not taking any manners.
Dear rude old men, don't respect people's manner.
