Casey's is a convenience store that offers quick service and a variety of items. Customers appreciate the surprisingly delicious subs and the convenience it provides for those on the road. The staff members are friendly and helpful, with one employee going out of her way to assist a customer after foot surgery, which left a positive impression. However, the store has some issues with cleanliness and stock. The tea machine was reported to be very dirty and not cleaned for a long time, which customers found very unpleasant. Additionally, the store has been out of certain protein drinks, like Muscle Milk, for over three weeks despite repeated mentions. Overall, while the staff's helpfulness is valued, improvements are needed in cleanliness and stock management to enhance the customer experience.
