Exxon, located at the 7-Eleven on East Independence and Matthews-Mint Hill Road, offers convenient fuel options with reasonable prices. Customers can typically find gas pumps quickly and enjoy a nice variety of snacks and food inside. While the customer service is generally decent, there are significant concerns about the cleanliness of the restrooms, with reports of poor maintenance and unpleasant odors. Overall, Exxon provides a practical stop for fuel but may need to improve its bathroom facilities.
