ApoStructura is on point here. I've seen it all: Someone walks in a parking lot and trips and falls over the curb. "It should have been more visible!" So, you paint the curb bright yellow and next someone slips on the paint. "It shouldnt have been painted!" Walking into the store, someone trips and falls over the corner of a floormat. "There shouldn't be a mat there!" But once the rug is removed people slip on floor because it gets too wet. "There should be a rug to wipe your feet!" So you permanently place a "Wet Floor" at the entrance instead, but then the argument because "that sign is always there, even when the floor is dry, it carries no meaning!" No matter what you do: lawsuit. And because layers cost $500/h, it's often cheaper to settle than it is to try and win. Which, in turn, drives more lawsuits. Americans are largely unaware of just how dysfunctional the tort system is and how it sucks the lifeblood out of everything.
