Riding the MRT... the decision-making process

Everyday when I ride the MRT, I actually have to make several 'important' decisions. I'm not kidding! (Ok, maybe only I think of these things, but they do make a difference! :P) It's kinda like betting, even though there's no money involved. What you do 'lose' is the extra energy that would have be expelled from either walking / standing longer than is probably necessary. :P

Ok, here's what I'm talking about:

First of all, when you go to the MRT platform, you need to decide - which section of the platform should I stand at to board the train? The front of the train, middle section of the train, or towards the end of the train? This decision will require an assessment of several factors:

1. Which MRT station(s) did the train just come from? - This will kinda influence how empty the various compartments of the train would be, and will determine whether you actually have a chance to even board the train!
   
2. Which MRT station are you alighting at? - You wanna be strategically located at your destination station so that when you get out of the train, the escalator to the exit should be right in front of you! :P
   
3. Is the door of that particular compartment positioned in the middle of the compartment? - This is so that you have more chance of accessing an empty seat. For example, if you enter at the door that is near the end of the compartment, one side would be the connector of the compartments and will have only 4 available seats. As opposed to entering in the middle of that compartment, you'll have more options to your left AND right. ;)
   

Now, assuming you've chosen which door to enter the train. As the train comes to a stop, you notice that both sides of the door you are about to enter have empty seats. Great! OK, the second decision you have to make is: Should you go left or go right? You look around and assess the people around you. You look to the OTHER compartment doors and assess the people there: Will they be heading to those same seats you are targeting? You would probably want to choose the direction that you think least people would head towards so that (hopefully) those empty seats will still be unoccupied by the time you reach it! :D (Ok, some of you are probably shaking your head at me right now... but bear with me. The 'torture' will end soon. :P )

And suppose the 'worst' has happened: You do not find a seat. No problem at all. But now you're required to make ANOTHER decision: Where should you stand? You may think that this is ridiculous, but this is actually the difficult part, as you need to gather all your past experiences and intuition, and of course with (a lot of) luck, to assess the people who are currently seated. Assess their clothing (work clothes, school uniform, housewives?) , what they are carrying etc, and try to guess whether they are going to alight soon... you want to be standing in front of these people so that you can take over their seat when they stand up and leave the train. :)

Ok, so this 'decision-making process' is not an exact science, and most of the time it's just pure luck. But it's something I thought is quite interesting (and funny!) and wanted to share. :P I'm sure everyone does it to a certain extent! Well, I know I do... :P
