A stubber is a device on which one can stub out their cigarette or cigar. In the past, they often had "stubber" written on them and were used in buses.[1] An other use are plane plates at bus stops and train or underground stations.[2] The difference between an ashtray and a stubber is that a stubber is not able to contain the ash and usually is designed as a plane plate[3] or an inclined rough surface. In February 1990, smoking was banned on the London Buses[4] and following the stubbers in the buses came out of use. Today they are still in use on top[5] or beside of public ashtrays.[2]
