Obviously not. Again, they can get his information, whether it's an ID, their season pass, etc. This way if it is reported stolen later, they have the thief's info. Obviously, if it truly the person's board, they've got nothing to hide.
It's a brightly colored $500 board which A LOT of people know and love, hence the lock. Pretty simple concept, really. I can afford just about any board or piece of equipment out there, and have bought a couple of the $1,000+ boards, but the skate banana is the best all-around board for in-bounds resort/park riding I've ever ridden.
