I watched a pit terrorize a small maltese yesterday on a train not unlike this MUNI bus. The scene was sad and frightening and dumb all at once. The owner could hardly contain the fierceness of his dog. Eventually the train conductor asked/demanded the guy move to the back or get off. Two stops later another guy with a pit tried to board and the conductor flat out said “NO.” As discriminatory as it was, everyone in the front of the train cheered.
