Circle K at 1525 Caulks Hill Rd in St. Charles, MO, is a convenient store and gas station that offers a variety of products for people on the go. Customers can enjoy a good cup of coffee, cold beverages, Polar Pop cups, Froster drinks, and fresh food to go. The station provides premium quality fuels and has an ATM for added convenience. The staff is generally friendly and fast in service, and the store is often praised for being clean and well organized. Customers appreciate the ability to get cashback through apps and the low gas prices compared to nearby states. However, some concerns include dirty bathrooms and the way the entrance and exit are built, which can be inconvenient. A notable positive experience involved a helpful manager who returned a lost wallet without accepting a reward. On the downside, some customers dislike the $100 hold on debit cards for gas, feeling it is excessive and not practical for everyday spending. Overall, Circle K is seen as a decent place for quick stops, with good service and affordable fuel, though it has minor issues that could be improved.
Parking lot is a pain to maneuver but they have great gas deals and you dab use upside for additional discounts. Bathrooms were below average and needed to be cleaned badly...

Love this gas station. Employees are so friendly and they got some really good hot snacks to choose from. Their pretzels, when fresh, are sooooo good!!
