Sometimes I walk up the escalator, if there's nobody in the way. I'd never make any effort to pass anybody; it's at most a ten-second ride. And sometimes, if I'm tired, I just ride it.
10 seconds is often the difference between catching the subway and having to wait for the next one. Blocking the way is incredibly rude imo unless you're carrying something bulky or so (and even then you should make at least a token effort at trying to let people pass who are in a hurry).
Anybody can pass me any time they want; what I said was I wouldn't try to pass anybody else. And ten seconds can make the difference when running for a train? Big deal. So can the train running ten seconds slower or faster. So can the number of people going through the turnstyle ahead of you. So can stopping to sneeze a couple of times on the way to the station or holding the door for an old timer carrying a shopping bag. "Sorry, lady, gotta beat the clock."
Thump. Seriously, I think people these days
look for things to get uptight about. Slow down. Mellow out. Repent, Harlequin.
