Golf has a rulebook thicker than most novels so it’s no surprise that players get rulings wrong from time to time. That’s understandable. However, certain habits should be against the rules. They may not cost anyone penalty strokes but they’re annoying enough that maybe they should.
Golf is supposed to be fair. It’s supposed to be respectful. But it’s not if you’ve got any of these habits.
Taking divots on practice swings
If your practice swing accidentally catches a little turf, it happens. But if you’re the kind of golfer who takes two or three full practice swings that dig up flounder-sized chunks of grass (and then don’t even fill them), you’re part of the problem.
The practice swing doesn’t need a big old chunk of earth to be effective.
While we’re on this topic, if you’re making a practice swing with your driver and taking chunks out of the tee box, you may want to take a lesson.
