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 provided by many clubs is for a customer to be placed on stage with one or more dancers for a public lap dance. Occasions for this type of performance are bachelor parties and birthdays, among others. Bed dance areas require more space because they are designed for the customer to be prone with the entertainer(s) positioned on top of them. Bed dances are the least common of the three, and in many clubs are a more expensive option than a lap dance because of the novelty and increased level of contact between customer and service provider.
