Remebered two more: the US Postal Service. If it requires more than a single stamp to mail, I'm going to UPS or FedEx. Those USPS idiots lost three separate packages over 3 days and cost me more than $300, and when I complained, basically said "tough shirt." Everytime I read a story about them failing, I smile.
Blockbuster: I couldn't be happier that they're dying a slow death. I returned a movie once, only to have them claim that I did not and charge me $25 to replace it. When I protested, the manager screamed at me, quite literally screamed at me, and basically said "Pay the fine, kid!" Again, I smile every time I drive past a shuttered former Blockbuster. Karma, baby, karma.
