Oil Companies Sue Circle K Corp.: A group of property owners and two oil companies--Thrifty Oil Co. and Golden West Refining Co.--filed suit in Superior Court on Wednesday against the Circle K Corp. alleging that the Arizona-based operator of convenience stores breached its 15-year property leases and gas purchase agreements at 88 sites around California. Circle K has not paid any rent on the properties since Jan. 1, said Donald Smaltz, the plaintiffs’ attorney. Circle K officials could not be reached for comment. (Filed Feb. 21; Case No. C747508)
