Phillips 66 found that locations that received monthly mystery shops, along with reports that pinpointed action plans for improvement, reported higher customer satisfaction. As a result, the company is rolling out its Retail Excellence Program to all 8000+ locations. Operations will be assessed with monthly mystery shops and consumer input captured in surveys. These results are coupled with financial data, and powerful, predictive analytics to pinpoint what matters most to consumers and what specific changes at each location will have the biggest impact on sales.
Five years after Akerlof's paper was published, the United States enacted a federal "lemon law" (the Magnuson–Moss Warranty Act ) that protects citizens of all states. There are also state laws regarding "lemons" which vary by state and may not necessarily cover used or leased vehicles. The rights afforded to consumers by "lemon laws" may exceed the warranties expressed in purchase contracts. These state laws provide remedies to consumers for automobiles that repeatedly fail to meet certain standards of quality and performance. "Lemon law" is the common nickname for these laws, but each state has different names for the laws and acts, which may also cover more than just automobiles. In California and federal law, "Lemon Laws" cover anything mechanical.
