Casey's is known for its great food and friendly staff, with clean stores where employees are always attentive. Customers enjoy the excellent coffee from the new machines, often calling it the best gas station coffee they've ever had. However, there are some issues, such as difficulty reaching the store by phone, which has frustrated some customers. Additionally, the store's policy on diesel pump limits at high prices has caused inconvenience. Overall, many appreciate the positive atmosphere and quality service, but improvements are needed in customer communication and pump policies.
