At least I didn't have to pay for it. There was no one to collect my fare when I entered at the middle door of he car.
But they way home was a much more pleasant experience. Well, as pleasant as one can have on the T.
Our driver stopped and opened the door for someone who almost missed the train. She waited until a family had settled in with their stroller and several small children after they almost went flying across the aisle. After calling a middle aged couple up to the front to pay (I think this was around Fenway), she was gracious about their mistake upon learning that they were from Western Mass.
