I have long believed companies that romance their employees succeed in the marketplace because their workers in turn romance the customer. Now the latest results of the American Customer Satisfaction Index (ACSI) bear out my belief.

In the past, the ACSI people tracked companies that have done well in their survey data and determined that those stocks increased over time at about three times the rate of those companies who didn't score well.

This most recent ACSI took a look at the financial sector, among other industries. Their findings reveal that the bigger the bank, the worse the customer service.

The average bank gets a score of 77. Bank of America has been singled out as the worst bank in America with a score of 66. Right behind Bank of America are Citigroup and Wells Fargo.

One monster bank that did substantially better than others was JP Morgan Chase with a score of 74. Yet credit unions take the cake with an average score of 82. Of course, it's important to note that even credit unions can vary in quality.
