For non-smokers, the smoke stops can provide a wealth of entertainment, starting when the Conductor announces a very short upcoming smoke stop. When the train stops, stand back and enjoy the near panic as smokers fight to get out that door and use every second on the platform to power smoke faster than you would think physics allow a cig to burn. Add in rain or 20 below windchill for a bonus.
Then when they board, count all the butts on the ground, not all of which are stamped out.
I can understand the addiction. I can't understand the piggery of so many smokers.
I still remember in Atlanta at one of the freeway exits. There were literally thousands of butts at the light. Why? Not only did the smokers take the red light as an opportunity to flick away the butt but they decided it was a good time to dump the ash tray!
