The photo I just took yesterday afternoon shows the worst manners of all. I was riding from Daly City to Downtown Berkeley on the Pittsburg/Bay Point line and found this guy sleeping on the train by laying on both of the seats. He then proceeded to put one of his feet up against the window when the train was going through the transbay tube up until I had to transfer at 19th Street.
I thought the BART seats was infected with all kinds of nasty bacteria. Surely I don't want to lay my face on one of those funky seats.
