You have brought out a very valid point of view. I have on a number of occassions come across such an unbecoming behaviour. I did try to speakout and correct the situation but was awashed with the callous attitude of fellow citizens. In one incident I even came across a Japanese lady breaking lines and pushing her way through. I wonder if our attitude had rubbed off on her!
We must check this behaviour as and when we come across them even at the cost of looking like a world police.
