shift. Less formal clubs will have dancers take turns when a stage becomes empty or have a free flow of entertainers where the stage has any number of entertainers who wander off and on at will. Featured entertainers are not usually part of the rotation and they generally have set times when they will perform that are advertised throughout the shift. If a DJ is present, he or she will emcee the rotation and typically announce the current dancer(s) on stage and possibly whom to expect in future sets. Private dances In peep shows, done with a customer seated in a private booth separated from a dancer by glass or plastic, there may be no music playing during a performance, in which the woman removes her clothes and displays her body to the customer. In clubs which offer lingerie modeling shows, which are peep shows where a dancer privately dances and strips for a customer, typically without a barrier, performances can also be done with or without a formal stage or music. Private dances in the main club zones most often take the form of table dances, lap and couch dances, and bed dances among others. An air dance is a particular form of private dance where little-to-no contact between the dancer and customer occurs. This class of dance spans the different categories above and some dancers may perform air dances when more contact-heavy forms of dance were expected and paid for. Club management may set standard prices for the various dance services, but individual strippers, where permitted, will negotiate their own prices, which may be higher or lower than the advertised rate. Table dances are distinguished from other forms of dances in that they can be performed where the customer is seated, on the main floor. Table dance may also refer to a form of minimal-touch private dance where the performer is physically located on a small table in front of the customer(s). Table dances should not be confused with table stages, where the stripper is at or above eye level on a platform surrounded by chairs and usually enough table surface for customers to place drinks and tip money. Where offered, lap dances are performed in all manner of locations and seating, ranging from plain stools and kitchen-grade chairs to plush leather armchairs. They can also be performed with the customer standing in these designated areas. A service
