Keep away from the sharks

This sign is posted as part of several warnings including rip tides and not turning your back to waves. Somehow, it doesn't seem right though. I can understand playing with some wildlife, but gosh, playing with the sharks sounds flat out dangerous. I don't think people have much say in the matter though. If a shark is out there about to nibble on you, I don’t think it’s going to ask you first. Yum, human drumsticks, high in fat, lacking vitamins though.
