Unchained YOLAW

There are defenses for Negligence liability.

For example, if you notice that a bottle of fruit juice has spilled in the aisle of your grocery store and you block off the aisle with a rope and put up a sign reading, "Danger: Do Not Enter," and a customer ignores the sign, removes the rope, then injures himself, you can defend against liability by stating that the customer assumed the risk by disregarding the warnings you put in place.
