Love or hate his personality/antics, PDW is probably the most talented bowler of all time up to this point. The fact that he was still right in the hunt at yet another major goes to prove that. I'm not a fiery, in-your-face type of guy like Pete; however, that doesn't mean it's wrong for people to be that way within reason.
Pete didn't run up on the approach and threaten to knock Belmo out for putting his towel there. He asked the tournament directors to enforce their own policy. Heck, I've seen fist fights and near fist fights during league bowling over things that were even more trivial than towelgate, so let's not act as if Pete's behavior was grossly out of line. Was he a bit childish/unprofessional, maybe, but is that any worse than Rash screaming "bottle bi#tch" at Belmo a few years back? Is it worse than Walter Ray whining about the conditions every time he leaves a 10-pin? Is it worse than hearing Bill O'Neil mutter under his breath about how badly the guys in the previous matches broke the lanes down? Bowlers, even the best ones in the world, are human beings, and human beings get frustrated from time to time. Pete got frustrated, and he acted like a bit of a baby. It's not the first time that's happened (to him or any other bowler), and it certainly won't be the last.
Lastly, Interstate4, you need to realize that for every person like you who dislikes PDW because of his attitude and antics, there are just as many if not more people on the other side who like him specifically because of those very things. As such, while I appreciate your initiative in letting Storm know your thoughts, I wouldn't count on seeing Pete's lightning bolt pulled anytime soon.
