Of course it wasn’t self-inflicted. But that doesn’t mean Walmart is culpable. It means it was an accident and sometimes we have to grow up and deal with the consequences of accidents.
If the Walmart employee had dropped the can on her foot, sure, there is probably some issue with culpability, responsibility.
But anyone who has shopped at a store in the US in the last 10 year knows that the plastic bags suck. Period. And the bag manufacturers and stores were hounded into using those bags by the environmental lefty whackos. If you want to hold someone accoutable, hold them accountable.
Given that these bags suck, when I go to the store, I tie up my bags when I am leaving; I double bag heavier bags; I don’t have them put things like a gallon of milk in a bag because that would be stupid.
It does not always work that way, especially when you knowingly use crappy bags and your employee over loads the bag resulting in death.
I am certain the woman sought medical attention, few with a broken toe would not.
She may have gotten Staph at the hospital.
But I don’t see how the shopper was negligent and nobody else is.
Plus, every chain including Walmart sells polyester fabric shopping bags and encourages people to use them. Some stores even give nickel discounts for using "green" recyclable bags instead of paper or plastic.
