I'm sitting on the train, headphones on, playing a game on my Windows Phone, as normal, when I hear a demanding voice from over my shoulder say, "Do you see that sign!?"
My brain attempts to disengage from my virtual world and process this. Usually, when a voice like that is heard, it's from the train police, asking to see passengers' tickets. But wait, that's not what he asked for. Do I see the sign? There are a few posted signs asking for certain behavior. I'm not playing loud music, I'm not eating or drinking, my feet aren't on the seat… Ok, something's wrong, and I guess I need to turn to this mysterious voice and figure out what it is.
I turn and see an elderly man, looking a bit angry, glaring at me, with his finger pointed at the sign that indicates priority seating for elderly or disabled passengers and asking to comply with all requests to vacate the seat for a disabled passenger.
So, I figured I'd give him the opportunity to request my seat. "Do you want to sit down?"
"DO YOU SEE THAT SIGN?" he yells again.
The people in the rear-facing seat across from me offer their seat and practically stumble over themselves to get up and move to one of the several other vacant seats on the train. "No, I can't sit backwards," the old guy complains after them.
"All right," I said, giving up on any chance of civility with this curmudgeon. I stand up, turn around, and sit in the hastily-vacated rear-facing seat.
The old fart then sits down, pulls out a 12oz Coke bottle, and starts drinking it, right under the sign that says "No Eating or Drinking".
I guess he didn't see the sign.
