If you ride BART daily, I'm sure you've noticed the "thank you" BART ads around the trains. One of them says (can't remember the exact words), "Thank you, sleeping behind your sunglasses riders," and another says, "Thank you, first ride of your life riders." I think there are a couple others, although I can't remember them ride now.
I think they are a bit corny but not close to being as bad as the SF Giants' "It's your Giants" radio and TV ads (side note: speaking of the Giants, depressing 9 straight losses. I hope we release Benitez to make a statement, waste the millions who cares, just rid the cancer). I know that BART is trying to express appreciation with humor, but I remember thinking these two ads that I've seen do not actually directly relate to me and frankly, slightly lame.
BART should have ads that thank those of us who know to walk on the left and stand on the right, those of us who have tickets ready in hand BEFORE we approach the gate, those of us who actually make a point to get up for seniors and handicapped, those of us who ride BART the next day despite horrible delays the day before, those of us who recycle newspaper in the proper bin instead of leaving them on the train, those who pay daily for parking, and those of us who write/comment about BART!! :)
