For our list of coffee chains in the U.S., we started with the 20 chains that have at least 25 or more locations either within a state or in different parts of the country. Then, we gathered the Better Business Bureau’s (BBB) ratings of the different coffee chains across the U.S. (Scores were available for 18 of them.) The BBB uses public data, as well as information provided by companies themselves, to assess how well a business serves and interacts with its customers, such as the volume of complaints received from customers, whether or not those complaints went unanswered or unresolved, and if there is evidence of a pattern of failure to address complaints. In its overall assessment, the BBB also considers the transparency of a company’s business practices, competency licensing, advertising, and government action. The resulting ratings are provided as both a letter grade, as well as a numerical score on a 100-point scale, both of which we’ve included in our analysis. We also included, where applicable*, the number of stars a brand received on the popular review site Trustpilot. Lastly, we calculated the average Yelp rating for the locations in the state where each company’s operations are based—in other words, where the brands are headquartered. (In the case of Tim Hortons, which is a Canadian brand, we used their Detroit locations based on the significant presence the company has there.) Both sites have five-star rating scales. Finally, we gave each metric a weighted value before running them through our exclusive algorithm to see how each brand scored on our 100-point scale Dissatisfaction Index—with a score of zero indicating excellent customer service and 100 representing the worst.
