I suppose that they are trying to use the following Gaming regulation in your case.

Regulation 12

#12.060

Paragraph 4

A licensee shall not redeem its chips or tokens if presented by a person who the licensee knows or resonably should know is not a patron of its gaming establishment, except that a licensee shall promptly redeem its chips and tokens if presented by:

a) Antoher licensee who represents that it redeemed the chips and tokens from its patrons or received them unknowingly, inadvertently, or unavoidably;

b) An employee of the licensee who presents the chips and tokens in the course of employment; or

c) A person engaged in the business of collecting from licensees chips and tokens issued by other licensees and presenting them to the issuing licensees for redemption.
