Some people that have played forever take a long time to play. Beginners that play with these experienced slow golfers learn to play slow. Golf courses, themselves, are not nearly vigilant enough on slow players. Courses are afraid if they're too hard on the slow golfer, they may not come back. Well, I'm here to say that if they're not hard enough, the rest of the golfers may not come back either.
Some courses add to the problem with their cart policies.
Anytime you have to stay on the cart path, you run the risk of having golfers walk back and forth across fairways trying to choose the correct club. Golf courses state that the golfer should take three clubs with them to their ball. This is a great idea and should be heeded. However, every time I agonizingly watch from the tee box, it seems like all I see is players moving horizontally back and forth across the fairway and rough. And then there's the problem of everybody in the group moving from ball to ball.
