I have never taken kindly to going through road checks and having a cop stick his head in my window to smell my breath.
Now when I pull up to one I roll down the window enough to talk but not enough for him to stick his face in uninvited
I have been asked to roll it down and my answer is the same...it is down.
A couple years ago i did this and when he was making his move to stick his face in my window I offered him my breath by way of gently blowing some breath at him.
He freaked out and ranted about me possibly having a disease and giving it to him...when he askled why I did that I said that I was helping him out be saving him the effort of sticking his face in my car.
He freaked out a little more then told me to Get the F outa here.
