Frankly I find it absolutely deplorable that the T ignored its stuck passengers to the point where the passengers felt like they had to evacuate the trains themselves. That is terrible customer service -- hell, it's not even service at all -- and staying in the trains could have posed a serious health problem if someone had panicked, or if someone had passed out, or otherwise required serious medical attention while stranded on the tracks, especially in the Kendall tunnel if there was no cellphone reception or any way to call for help.
So the next time Danny Boy Graubaskas pipes in on the station intercoms with his pre-recorded "it's your job to keep us safe from the terrists" announcement and begins his inane speech with the useless platitude "Safety is our number one concern at the T", if you hear someone in the station loudly coughing "BULLSHIT!" that person will probably be me. Because it's clearly obvious that's not the case. I wholeheartedly encourage you to join in on the coughing whenever you hear that.
