Subway Over-Optimizers

I'm amazed at the way subway passengers will not only try hard to get a seat, but once they have one, will keep moving every time a 'better' seat nearby opens up ('better' meaning as far from other people as possible). Sometimes this is justified, as when there's a big passenger who really takes up a seat and a half, and it gets a bit uncomfortable. But I see it more and more when there's no such circumstance. In these cases I guess people are just really antisocial, or perhaps they're trying to assert their primacy over the people getting on at the next stop, since they usually have a better shot at the newly available seats.
The other night we were on the A train and there were no seats when we got on, but things started to clear up as we headed uptown. At one stop, a bank of three seats next to a door was emptied. On the other side of that door, a man was sitting in the seat nearest the door, with no one next to him, and an inoffensive-looking person two seats away in the third seat. We started to move toward the empty bank. This guy apparently could not stand having someone two seats away from him, so he quickly got up and darted over to sit in the other bank, again nearest the door. We got there after him, but I think if he had looked around he would have seen us heading for those seats. We still sat down, so now thanks to his over-optimization, he had two people right next to him, worse off than before. Boy, he must've felt pretty dumb right about then! Yes...
Later in the ride, the pair of forward-facing seats next to our bank of three opened up. Normally I would've considered taking this opportunity for optimization, because for some reason I really like those seats. But this time I decided to stay put, just to teach him a lesson. Jerk.

The next morning I had a much more pleasant transportation experience. An old guy with white hair, a straw hat, a checkered shirt and a banjo got on the bus at the same stop I did. He noticed a pair of little girls looking at it inquisitively, and asked if they knew what it was. A minute later he was leading a little singalong. Another child joined in a few stops later. He played and sang softly, and no one seemed disturbed by it. The bus driver took no notice. They got off at 231 ST, and he said maybe he'd see them again the next day.
