My encounters had led me to believe people are very slow in terms of processing visual information.

One example would be, a narrow corridor in a packed shopping mall. A crowd of sloths stand in the middle and start talking, despite several people accidentally nudging them just to get across. These people couldn't care less and merely glared at the passer-bys as if they are never in a wrong.

Another could be eating on the train, I saw a young man,stuffing down a bread whilst watching his PSP,sitting down on the floor. Not only is he blocking people way,but he is doing something which is illegal.

One might argue that when confronted,they could reason, "If these people are bothered by it,why won't they tell us?" Only a small crowd would only either realised or after being told they are creating a nuisance then they correct their error. Yes,everyone has a part to play in common courtesy,so why not start from ourselves rather than wait for another to act first. 

P.S Speak nicely to the people who were unaware of their errors. Yelling at them as if they owe you isn't going to solve anything. In fact, it puts you in a bad light. :)

Another scene, I was at a fast food chain restaurant. People are queuing no doubt. I saw this person standing real close to the person in front ordering his/her food. I could even say half the body was leaning against the counter. I do not understand why one must go so close?In my opinion,I feel it is a invasion of personal space. Is it to shave a few seconds off to walk to a few steps towards the counter after the person in front leaves? It is a mystery....
