If you stumble on to the green drunk and disturb the players they are going to sous vide your ass in the water hazard.
They have a huge sign at the entrance, on tournament days one cannot have a cell phone, camera or any type of gadget in your possession, if your caught you will be escorted off the course without refund and your "credentials" (they don't call them "tickets") will be revoked, permanently. The reason the prices are so high is once you have "credentials" you get them year after year, my brother got his after waiting in the "lottery" for 10 years, he sells them now every year at a handsome profit.
