I know that the T is very difficult to navigate when one has a mobility problem, especially at Porter Square. I also know that sometimes it's important to chat with the newspaper vendor about recent sports news, and that's all well and good. But is it entirely necessary to have this discussion with you planted blocking access to the up escalator?
Granted, it was the shorter escalator from the mezzanine to outside, but still, I didn't want to walk up the stairs, and I felt churlish shoving past you. I did say "excuse me", and I don't think I actually made physical contact (I hope), and I completely understand if you needed to hold onto something to steady yourself, but I would think that something more stationary than a moving escalator rail might be more useful for that purpose.
