They also have a name for not paying slip-and-fall claims. That earns them a powerful enemy in the plaintiff's bar.
I wonder if that isn't where most of the bullshit you read about them comes from.
It's not just slip and fall claims. On all legal matters, they do a cost-benefit analysis. On paying a lot of their bills on time too, which hurts their vendors. They're Wal Mart, what are you going to do, turn down their business when they don't pay?
