LRT passengers and LRT in KL

I was thinking during my ride in the LRT to work the other Saturday morning, why there is an empty seat next to the chubby fellow and why no one wanna sit next to him.  Does this show Malaysian is obese society OR THE LRT in KL IS JUST TOO SMALL??

but that evening when I took LRT back home I see another phenomena, Malaysian just don't know how to sit nicely and be courteous!!!

courteous = having or showing good manners; polite. http://dictionary.reference.com/browse/courteous
