This chapter does not apply to any municipality having a freeholders' charter adopted and ratified under the Constitution and having in such charter provisions for the issuance of franchises by the municipality, but nothing contained in this chapter shall restrict the right of any such chartered municipality to avail itself of the provisions of this chapter wherever it may lawfully do so. The provisions of this chapter relating to the payment of a percentage of gross receipts shall not be construed as a declaration of legislative judgment as to the proper compensation to be paid a chartered municipality for the right to exercise franchise privileges therein.
