If I'd been his caddie, I would've refused to pick the club up. Major league douchebag play from someone who was clearly wanting a reaction, and I gave him one.
If nothing else, act like you've fucking been there before. My god... it's a good thing he's wearing soft spikes, otherwise he would've pierced his goddamned lips while walking.
I mean, if life is that tough on tour - find a new gig.
