Driver tried this one day and almost got assulted. Guy in back holdin unlit cigarette like ya would if it was lit driver seen it in mirror n stops n words exhanged but finally started moving. Now here the twist im at thet front of the bus also with unlit cigarette but mine was cupped in hand. Most likely driver smelled mine n seen dude in that back n swore it was lit. But yeah us smokers know to extiguish before boarding seen a few smoking pockets n cigs that werent fully out. Its only the ignorant,drunk, or drugged up that try to do it on the bus
