It appears that the Chickasaw Nation, which operates several of the larger casinos in Oklahoma, wants all customers to giveup their rights as a US citizen. To play slots or participate in most casino events you are required to have a players card. Following is the last sentence in the application form, which is above the signature line.
"The applicant consents to the jurisdiction of (chickasaw)Nation's law and judicial system without limitation to time or event."
They demand the same type of agreement from anyone during business with their casinos, before they will pay any bill for services, advertisement, tv ads, supplies, etc.
