in my opion, because of the nature of the job duty of pulling someone over. the officer can expect the worst at first and be what some might concider firm, rude, abrupt... its all personal opinion but if you communicate well with the officer and you are not seen as a threat and you have not endangered anyone and you show respect to their atthority then you will more times then not have a polite helpful officer that might let you go. getting pulled over is like a job interview. your conduct can get you out of a ticket or get you ticketed for every violation the officer finds.I would say expect all officers that pull you over to be rude to an extent, but dont take it personal. you will run in to some nice ones, but no one ever likes to be pulled ove so it normally feels like a bad experience. It was kind of the officer to affix the tag for you so, he wasnt all bad.
