How to obtain the Secret Ticket from Zack  - 
The Secret Ticket allows the character to pole dance in the casino.

First, the entire pole dance scene must be unlocked. To do this, you must bet 3000 Zack dollars on Christie's slot machine, and you must hit the jackpot a total of 9 times. In order to bet 3000 Zack dollars using Christie's slot machine, you must have a minimum of 1.5 million Zack dollars, otherwise the machine will not be powered on.

Once the entire pole dance sequence is shown, on the following night, Zack will give your character the Secret Ticket which allows her to do the dance. Once it is used, it will disappear, and the only way to get another ticket is to hit the jackpot 9 times again.
