Take note of where everyone's ball is and then be careful to stand where the balls are probably not going to roll. Just apologize and thank them for helping you understand the rules.
As a beginner, you will surely stand on the persons intended line to the hole. People get very sensitive about standing on the line that their ball will roll on. VERY IMPORTANT: Notice where the other players balls are on the green.If it takes longer than 10 seconds to drop in, you count that drop into the hole as a shot. If your putt stops just on the edge of the hole, you can wait 10 seconds to see if it goes in.Another rule a lot of golfers break when they move the ball an inch or so closer to the hole! Get caught doing this, and you'll have no friends on the course! Always replace the ball as close to the identical position it was in before you marked it.
Remember to replace the marker to the original position before you play! Place the heel of the putter head next to the marker and move the marker to the toe of the putter.
