Where do people out cigarettes when there's no ash tray ?

I'm assuming you mean when you're inside a house as opposed to standing outdoors where you could put them out on the ground? I don't smoke inside my house, but when I used to I put them out in a toilet or a sink. Failing that, using an aluminum can or glass bottle usually worked ok. That's what I use in a vehicle with no ashtray.

Hey , They do what ever they can with them . Step on them , or flick it out of the car ya know . I have seen it all . My brother when he use to smoke he would put in a pop can or someting like that .

I've mostly seen people flick them any old play, away from people of course. I freak out about potentially starting fires because I'm crazy, so I usually spit and put it out in that (gross, sorry) and then no worries about throwing it in the garbage bin.
