No. NOBODY smokes in my car !
I once had a friend who didn't believe that when I said it. He kept on insisting that I would drive with the windows open....on the motorway!
So I finally got tired of his nagging and kicked him out and drove on. I tuned on the next exit 10 minutes later, and passed him on the other side. He was still standing there (but he hadn't seen me). So I turned back on the next exit and picked him back up. He'd been standing there for a good 30 minutes. Keep in mind that this was before the breakthrough of GSM phones, so he really had no place to go or no-one to call.
At that time he was pretty pissed about it, but at least he'd lost his appetite for smoking!
Actually we reminice on that story quite a lot, but we can all laugh about it now.
Oh yeah, my friend has also stopped smoking since then...
