A widely cited U.S. local ordinance is San Diego (California) Municipal Code 33.3610, specific and strict in response to allegations of corruption among local officials, which included contacts in the nude entertainment industry. Among its provisions is the "six-foot rule", copied by other municipalities in requiring that dancers maintain a six-foot distance from patrons while performing. "Fully nude" clubs may be subject to additional requirements, such as restrictions on alcohol sales and "no-touch rules" between customers and dancers. To circumvent these rules, two "separate" barsone topless and one fully nudemay open adjacent to one another. In a small number of states and jurisdictions where it is legal for alcohol to be consumed but not sold, some clubs still allow customers to bring their own beverages.
