Exxon is a gas station and convenience store that has received mixed reviews. Customers appreciate the clean and well-stocked store, as well as the great customer service, especially after a management change two years ago. However, some have faced issues, such as inconsistent 24-hour service and long wait times at the register. One customer expressed disappointment over expired milk and slow checkout lines, highlighting that only one cashier is often available despite many customers needing assistance. Overall, Exxon offers a good shopping experience but could improve on service efficiency.
