It is an unconscionable practice for a storage warehouse operator to relinquish possession of a consumer's stored goods upon the condition that the consumer sign a general release or any other document of similar import, in which the consumer releases the warehouse operator from legal liability for negligent loss or damage to the household goods stored as a condition for regular delivery by the warehouse operator of the goods in the ordinary course of business. Nothing in this section shall prohibit a warehouse operator from securing a general release or other document of similar import where a consumer's personal property in storage has been removed from storage for the purposes of conducting a public sale of such personal property pursuant to the provisions of § 7-210 of the New York Uniform Commercial Code.
