Among clubs, there is a variety of different ways to deliver entertainment, and fee structures commonly differ between clubs. A cover charge (entry fee also known as a "door charge") is customary at many clubs, the amount of which can vary by factors such as day of visit, time of day, gender, and other factors. To make the charge more acceptable to customers, some clubs include bonus items in the admission price, such as drink tickets that can be redeemed once inside. Some clubs also have drink fees tied to interaction with performers. The bigger the drink, the longer the time permitted with the dancer. This practice is more common in European strip clubs and African or Asian hostess clubs. Champagne Room pricing (where time with an exotic dancer in a private room on the premises can be purchased) is a variation on that same theme.
