When Common Sense Is Sometimes Not Common!

I am getting really annoyed with some commuters who often dash into the train before passengers can get out of the train. When a bottle is full of water, don't you pour out the water first before you can fill in more water?

Similarly when commuters take the escalators. They should stand on one straight row on the left, so that commuters who wish to walk up can do so on the right.

Why is this daily scenario only taking place in Singapore.? I don't see this happening when I am taking the trains in London, Sydney, Melbourne, Taipeh, Tokyo, Toronto and other parts of the world. Is this phenomenum uniquely Singapore?

I guess, in Singapore, common sense is sometimes not common!
