bus comes when you smoke

For the smokers, have you ever experienced this: you were halfway enjoying your Marlboro moment when your bus came. What do you do? Do you extinguish the stick and put it back into the pack, or do you take a deep lungful of it, board the bus and let it out inside the bus?

That day I was on the bus when I saw this 2 boys in ITE uniform taking the last mouthful of nicotine before boarding the bus. The bus driver waited more than 5 seconds before opening the door.

I got a feeling the bus driver was waiting for the 2 boys to choke on their own smoke before letting them board.
