A Pennsylvania convenience store chain is the tops in the nation. Maybe it's Hoagiefest, maybe it's the coffee. A new survey says customers prefer Wawa as the country's best convenience store. The American Customer Satisfaction Index is out with a new customer survey that puts Wawa ahead of Sheetz, and ahead of every other gas station/convenience store in the country. Wawa scored an 82 out of 100. That puts them ahead of QuikTrip, which is based in Oklahoma, and Buc-ee's, which is of course based in Texas. Sheetz doesn't appear in the list til number six, with a score of 79 out of 100. This is the first year for the survey, and Sheetz fans may have something to say about the rankings next year.
