5.20.030   Presence of minors.
   It is unlawful within the city for the proprietor of any billiard or pool parlor to permit any person under the age of eighteen (18) years to play or engage in or be present at any game of billiards or pool, and it shall likewise be unlawful for any person under the age of eighteen (18) years to play or engage in or be present at any game of billiards or pool in any billiard or pool parlor within the city.
   The provisions of this section do not apply to any person under the age of eighteen (18) years who is accompanied to a billiard or pool parlor by his or her parent or legal guardian, nor do the provisions of this section apply if such parent or legal guardian personally presents a written consent to the proprietor of such an establishment. The written consent shall be in the manner and form approved by the chief of police. The proprietor shall file and maintain the written consent on the premises and shall produce and make same available for examination when requested to do so by the chief of police or his or her authorized representative. The written consent may be withdrawn at any time by the chief of police or his or her authorized representative if the minor having such written consent is found by a court to have violated any law, or is placed under the jurisdiction of the juvenile court, because of his or her conduct on or about the premises of the billiard or pool parlor. The proprietor may at any time refuse to recognize the written consent after giving notice to the parent or legal guardian. (Prior code § 8.01.003)
