When I was younger the local cops in Delaware county pa used to pull me over all the time because the guy I hung with was a trouble maker. It got to the point where I stopped carrying my make up with me, because every time I got pulled over this one cop would dump my purse on the hood of my car and wind up breaking it. I finally called in a favor with my old school chum who just so happened to be the daughter of a detective on the force. Once she talked to him I wasn't bothered again. Regardless, I was always polite and never knew not to ask if I was being detained. I was too frightened.
