I get on the 2,3 express subway at 96th street. Many days a local train pulls up, lets people off, many of whom are trying to transfer to the express.
Without fail they will make a darting, elbowing move directly across the platform and will stand directly in front of you right on the edge and do the lean way over to look for the oncoming train. The depths of the NYC subway are not a pleasant place to be during the summer granted, but why these people feel like they own the fucking place is beyond me.
