Actually I never noticed he only plays his own courses. And as you note golf courses would be bankrupt if they prevented cheaters from playing their courses.
When it's fun golf I don't really care what others do. Take a drop? Sure. Declare the bunker GUR? Whatever. What does bug me is people who try to stretch the rules when it is a tournament. Hey, we have to protect the field. I'd LIKE to give you a drop but YOU need to explain which rule of golf gives you that drop. Seems fair enough. And gimme putts for birdie in skins games are right out. If it's a tap in then tap it in.
