Thanks It is sort of like that here, I know the first time you get caught smoking they will either give you an official caution (which I think is what they're supposed to do) or just say don't do it again and send you on your way. I think it depends how good you're being in the first place, if you're just chilling out and talking they'll let you go but if you start getting rude and abusive or unco-operative they'll even arrest you.
