Circle K offers a mixed experience for its customers. At the Jacksonville location on Pulaski Road, the staff, including Miss Selma and Caleb, provide excellent service and make shopping enjoyable with great deals and friendly interactions. Customers appreciate the delicious coffee and diverse inventory, likening it to a smaller grocery store. However, the Main Street and New Berlin location has received negative feedback for rude and disrespectful service. Overall, while some Circle K stores shine with friendly staff and quality products, others may leave customers feeling unwelcome.
