Review for Rivermist Casino Review For Rivermist Casino Google User May 1 '18 at 16:13 Reported to the Oklahoma Tax Commission for failing to accept the OK Tax Commission 100% Disabled Veterans Sales Tax Exemption Card. They said they don't recognize it, even though state law mandates every business accept it. Per the Ok Tax Commission Website: With the passage of SB1084, effective August 25, 2006, vendors are now required to accept the Veterans Exemption Card. It's wonderful to be a combat wounded and medically retired Veteran receiving a Lawfully State Mandated exemption, with proper and valid proof, and a business basically say nope, screw Veterans, we don't accept this.
