So much for the "Americans love to shop" theory: The latest rankings from the American Customer Satisfaction index show that actually, we don't. The index has taken its biggest slump since 2008, driven primarily by our dissatisfaction with buying gas (really, who likes these prices?) and government services.

Certain e-tailers hung on to their high ratings, including strong showings from Amazon, Netflix, and Newegg. And such brick-and-mortar brands as Publix, Nordstrom, and Kohl's continue to shine. Brands that took a dive include CVS and Priceline.

Overall, the ACSI index dropped 0.5% to 75.3 on its 0-100 scale, the biggest fall in two years. And the index hasn't risen since mid-2009.
