And since it happened at Wal-Mart, we know that Wal-Mart has deep pockets as a target of the lawsuit.
Walmart doesn't own those machines. They are owned and operated by outside vendors, the usual arrangement is that the store gets a percentage of the cash-box collection.
All costs to buy, maintain, repair, fill and install/remove those machines are borne by the vendor.
I am told it is not all that easy to sue Walmart.
