What do you do with your cigarette when done smoking?

Well you don't want ot put a cigarete in the trash because it could catch other things on fire ( i don't smoke that is just commom sense. But what many places do have is an outdoor giant ash tray thing for them to put it in. If your McDonalds doesn't have one ask them to put one in, and then tell customers to put them there. Personally I don't think anyone should smoke because they are killing themselves but hope this helped!
