Longtime Austin convenience store chain bags new out-of-state owner This dog has had its day. A South Carolina company is bagging the Round Rock-based Wag-A-Bag convenience store chain. Charleston, South Carolina-based Refuel Operating Co. LLC announced May 5 that it had agreed to buy Wag-A-Bag LLC for an undisclosed amount. Wag-A-Bag, founded in 1964 by the Rabb family, owns and operates 16 convenience stores in the Austin area. “I am happy that my family’s business will be in good hands with Refuel, and that my employees have a bright future with a growing company,” says Cary Rabb, CEO of Wag-A-Bag. “I am confident Refuel will continue to provide our customers a first-class experience with our world-class staff. This is a tremendous opportunity for everyone as Austin and Central Texas continue to grow.”
