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.
