Bring Your Own Seat on MRT Train

What a way to secure a seat for oneself in crowded train of SMRT!
Saw this chap brought n a white bar stool at Chinatown MRT toward Pasir Ris during peak hour.


Time to be innovative and in future bring my own field chair for my weak old legs , aching whenever can't find a seat on board the train. 

And in addition to that, air-con of many of the trains are not strong or they want to conserve electricity.
