Circle K, a popular convenience store chain, offers a mixed experience for customers. While the staff is generally polite, the store's machines and facilities can sometimes fall short. Customers appreciate the quick and easy self-checkout, but some express concerns about the cleanliness of the bathrooms, with one reviewer describing an unpleasant encounter. The overnight staff has also drawn criticism for alleged unprofessional behavior, including touching customers' food and drinks. However, the store's offerings, such as the Arnold Palmer iced tea-lemonade, are well-liked by many. Overall, Circle K provides a convenient option for quick purchases, but the quality of the experience can vary depending on the location and time of day.
