I think people change their minds when they're faced with a ridiculous hospital bill for treating the injury. Their insurance pays the hospital bill and then sues the store for the amount paid. The parent isn't even really the one suing; it's their insurance company. That being said, it's not so terrible for the parent to push back a little. The company reduced their liability with the warning. Having the parent acknowledge the risk is a success for the employee.
