Somehow a homeless man got on the train and whoa, he carried a very pungent smell. The scent instantly permeated through the train and one by one, everyone seated near him quietly got up and walked to the other side of the train or to another car altogether. I was seated two rows from him. I tried to be brave about it and not let the scent get to me, but I couldn't do it after 2 minutes. I got up and slipped into a seat on the opposite of the trian. Many other passengers followed. Those who couldn't find a seat ended up standing on the other side of the train! Anything to get away from the smell.
After 3 stops, there were a bunch of empty seats around this homeless man. He didn't mind or notice. He was sound asleep with his feel hanging off the edge of the seat.
I'm not bashing on the homeless by any means! If they are paying to ride BART to go somewhere, then I think they definitely belong there, whether they smell or not. But if they are sleeping in a warm train, I think someone (train operator perhaps? or BART police?) needs to do something about it!
