I once took a bus from Penn Station to Atlantic City where riders were greeted by a sign with the vehicle’s only two rules: No Smoking and No Spitting. About five minutes into the ride, a guy across the aisle sparked up a cigarette, took a drag, and then spit onto the floor. This continued for the entire ride. Apparently, bus travel has improved.
