They someimes even forget to lock the door and then it's like a brick wall which has collapsed on you and you can't get any air.
YUCK :-(
Edit: Not that I have anything against smokers, they are also only humans.
The worst kind of smokers are those who ,just before the bus comes, take a big pull at their cigarette and then get onto the bus and blow all the smoke out.
Greetings and Enjoy
