Circle K in Lampasas is a popular stop for many travelers. The store offers cheap diesel prices, and customers enjoy a special deal where pumping over 100 gallons earns a free meal. The fuel pumps generally work well and are kept clean, and the outside of the station is maintained, though it may not look as new as other stations. Restrooms are usually clean, and the selection of drinks is good. Many visitors appreciate the convenience of the location and find the staff friendly, although the staff frequently changes. A common issue noted is the discrepancy between posted gas prices and the prices at the pump, leading to concerns about false advertising. Customers also use the store for sweet tea, but sometimes the tea is not sweetened or has flavor mix-ups, which can be frustrating, especially for those with health concerns. Overall, it is considered one of the better gas stations in town.
