Customers rarely, if ever, see the preparation of these props, since they are denied access to the backstage of a dancer's performance space by the layout of the club. A customer often wants a dancer to "drop the act", which makes them feel special and desired. This girlfriend experience can involve increased intimacy up to and including sex acts. Dancers are commonly aware of this customer desire for increased confidence, and may allow the impression that a customer is seeing their true selves. In reality, it is often just part of the act with little to no emotional attachment for the dancer. Cultural norms and policies Rules governing strip clubs and the overall adult entertainment industry vary around the world and formats sometimes are combined under a single roof or complex. In Bangkok, Thailand, the Nana Entertainment Plaza in downtown Bangkok is a large, four-floor compound with over 40 bars. Most of the bars are go-go bars with dancers in various stages of nudity. They are not formal brothels, since customers must negotiate without an intermediary, directly with the dancers, for services up to and including sex. Zürich, Switzerland, has legalized prostitution and its strip clubs throughout the city offer sex among their services. Differing from Zurich brothels, sex services via the strip clubs are typically performed off site. Eastern European strip clubs have a similar model. A .34-square-kilometer "sex zone" in Tokyo, Japan, had approximately 3,500 sex facilities in 1999. These included strip theaters, peep shows, "soaplands", "lover's banks", porno shops, telephone clubs, karaoke bars, clubs and more all offering adult entertainment services. In Dubai, a nation governed by very strict cultural norms and laws, there are several Indian strip clubs offering at least partial nudity. Dancers may tie their state of undress to the number of songs played. This could correspond to a bikini performance for song one and topless for the second. In a fully nude club, the sequence could be topless-to-nude over two songs, or any one of a number of other variations. In the United States, clubs are classified based on typical performances, zoning regulations, and advertised services. Zoning regulations in the U.S. can prove a challenge, with clubs needing to be a certain distance away from schools and other areas where minor children are known to congregate. These restrictions are meant, ostensibly, to curb exposure to activities that could negatively impact social development of
