There is some debate as to whether lap dancing is entertainment or a type of sex work. Critics of lap dancing allege that some club owners, by installing dark private booths and charging dancers steep stage fees, are covertly condoning and encouraging the sale of sexual acts between customers and dancers. This can be a concern if, as for instance in the United Kingdom, the club has a public entertainment licence rather than a sex establishment licence, and in jurisdictions where brothels are illegal. According to the UK paper "The Guardian", "Research shows that the majority of women become lap-dancers through poverty and lack of choice."
