I'm sure the sign is there to prevent them from being sued should somebody actually get clobbered, because the management will then be able to point to the sign and say "We warned them! We really did!" But, now that I'm warned, what steps can I take to avoid the danger they've been so kind as to advise me of? I mean, honestly... there's not much I can do here. It's either my time or it isn't.
I hate useless signage.
