The PGA provides guidelines to help golfers ensure a fair and enjoyable game. These include maintaining an equal pace with other groups, taking no more than 30-45 seconds between shots, and being aware of local course rules. Good etiquette also means volunteering to mark your ball if it is farthest from the cup or in another player's putting line. Players should mark the ball's position with their club heel and reposition the ball by moving the marker from the club toe to heel.
