1st World Country. No 1st World Manners?

Remember I was talking about our world class transportation? Taking the MRT over the past few days have led me to observe that the basic courtesy that was lacking from ten over years ago, is still lacking now. I still do not understand why the people getting on have to squeeeeeeze in, when there are obviously alot of people getting off, the painted yellow lines on the floor oblivious to them.

Maybe I've been abroad for a little too long. But seeing this sort of behaviour really irks me.
