Dancers continually interact with the customers in the club. They walk around and solicit drinks and lap dances, usually scanning the club floor to find the most lucrative customer to greet. The dancer qualifies a customer by sizing up their appearance and personal characteristics. Once the dancer identifies a suitable customer, she approaches, and attempts to establish a social relationship. Interaction can also be initiated by customers. Clubs generate revenue by cover charges, selling drinks, and other means. Dancers make most of their income from giving lap dances or VIP dances, where regulations allow. Otherwise, customer tips, at the stage, are a dancer's primary form of income. Dancers are entertaining the customers in exchange for money and employing all of the resources at their disposal to do so. They sell the fantasy of sex, but do not typically follow through with the act.
