Person A is golfing at a municipal course, with homes built all around it abutting holes. Person A hits a shot that lands less than 1 foot inside the property of an abutting home. Person A walks up to the ball to pull the ball off the property with his club, when person B, the homeowner, and who just happened to be riding his zero turn lawnmower at the same time, jumps off his lawnmower and runs up to person A and said the ball is on his property, so it is his ball now. As evidence of his authority, person B points to a sign that says the same thing. Person A says "seriously? the ball is like one foot inside your property line. You live on a golf course." Person B says he lives on a golf course and that he risks broken windows, the ball is his, and to take some golf lessons. Person A says fair point on lessons, but he didn't break his windows and that he would have paid for it if he had, and that he will be taking the ball, which he proceeds to do without stepping on to person B's lawn. Person B walks up to person A, probably one or two feet from him, and says, "you're really an asshole." Person A responds, "I would say the same thing about you." Person A proceeds to take a penalty stroke, and drops a ball outside of the property line to hit his next shot, and proceeds to do so and goes about playing the rest of his round. What say you HROT, who is the asshole, A, B, or both?
