A man (we will call him Bob) pulls into a self-serve gas station and is filling his car when a pick-up truck arrives on the other side of the pumps and a bearded man gets out and shouts at Bob, threatening him and cussing and calling him vile names.
Bob doesn't recognize the angry man and tells him that he has made a mistake. Bob then makes a mistake of his own when he turns his back on AM to attend to his car. The stranger hits Bob on the head from behind with a sap, knocking him to his knees And then closes in to do more damage.
