Wal-Mart is famed for its hardball tactics negotiating with vendors. Including, it seems the contractor they hired to store videotapes of their internal meetings. In fact, they've played such hardball with their former custodians that they have now been outbid for access to their own archive by the plaintiffs of lawsuits against them.
Under other circumstances, I'd be upset about the breach of trust here. But these are two companies that clearly deserve each other, and I'm pleased to say that they make a fine couple.
