Roadblock

When entering the train there's usually a preference order of location that goes in this heirarchy:
1) the corner seats because there will only be one person at most sitting next to you, you're close to the exit, and you can lean against the wall
2) a seat with an empty seat on the left and an empty seat on the right
3) a seat with a person on only one side of your body and an empty seat on the other side
4) any open seat
5) the standing spot in front of a corner seat because you can get the corner seat if the person leaves
6) The spot next to the doorway because you can lean against the wall without the need to hold onto anything
7) a standing spot in front of any seat
8) a standing spot where you can reach a handrail or handgrip for balance
9) a standing spot not in front of the doorway
10) any standing spot

Sometimes the people like to block the way into the train by doing an alternate version of spot #6. Instead of grabbing the spot and turning their body so that it's not blocking the door, they enter the train and barely walk to the side. They just stand there and slowly turn around so that they're blocking nearly the entire side of one door. When the roadblock occurs, it can become difficult for traffic to leave and enter the train. The roadblock can be especially annoying when it's caused by the person at the front of the line entering the train.

Today I saw one woman pull this stunt as she got on the train. She then stayed in front of the doorway until a few stops later. Maybe she was a pervert and liked the feel of people brushing against her as they squeezed to get in and out of the train. I think she likes to read manga about people standing in front of train doors. Her fetish is getting out of control.
