Would have been a lot more fun if the drunk 4some ahead knew the etiquette. They started out with an ice bag of beers. Refilled at hole 3 at the drink cart. Two would putt, go to their cart, then the other two would get out of their cart to putt. They'd run back onto the green after finishing a hole to take videos, pull up at a ball with 2 carts, sit and talk for 2 minutes, then take out a club. They spent an eternity at each hole looking for lost balls. Two holes behind. A marshal would be nice
