§ 206-b. Posting of rates for motels and motor courts. Every person, firm or corporation engaged in the business of furnishing public lodging accommodations in motels and motor courts shall:

Post in a conspicuous place or manner in each and every rental unit, a printed copy of this section and section two hundred six-a and a statement of the rental unit charge or rate charged by the day for the rental unit. No charge or sum shall be collected or received by any motel or motor court keeper for any service not actually rendered or for a longer time than the person so charged actually remained at such motel or motor court, nor for a higher rate of charge for the use of said rental unit than is specified in the list of charges required to be posted by the last preceding sentence of this paragraph, nor for a higher rate of charge for the use of said rental unit than the maximum rate posted or maintained on any outdoor or outside advertising sign pertaining to such establishment, provided such guest shall have given such motel or motor court keeper notice at the office of his departure. For any violation of this section, the offender shall forfeit to the injured party, three times the amount so charged, and shall not be entitled to receive any money for services or time charged.
