Don't mean to sound snooty, but there are pin placements that simply do not even come close to meeting USGA requirements for pin placements. There are many requirements, but here is one I'll bet some on this thread are referring to.
"An area two to three feet in radius around the hole should be as nearly level as possible and of uniform grade. In no case should holes be located in tricky places, or on sharp slopes where a ball can gather speed.
A player above the hole should be able to stop the ball at the hole."

Don't let it ruin your day...agreed. But don't be under the false presumption that the pros deal with some of these more extreme placements. They don't. At least not in tournament play.
