A contract between a vendor and a public establishment shall be invalid unless the vendor enters into the contract directly with the public establishment's owner, general manager, or a person with authority to enter into a contract as specifically designated in writing by the owner or general manager. The acceptance of delivered items by a public establishment from a vendor that includes an invoice stating the terms of a contract shall not constitute acceptance of the terms and the contract shall be void.
