Circle K is a convenience store that offers fuel and various products. Customers appreciate the friendly and helpful staff, with several mentioning cashiers who are kind and attentive, making visits enjoyable. One cashier was especially praised for her great service, and another employee outside was very friendly and willing to assist late at night. However, some experiences were less positive, such as issues with paying at the pump where the rewards system didn't work, and store shelves being empty, like the cooler with water. Overall, the store is known for good customer service, but occasional problems with payment systems and stock can affect the experience.
