At the disco you can buy or sell drugs to the bartender if you know the password which is the scrambled in the top left corner on the shelf. Although the password changes it uses the same words: tits, titties, tequila, whiskey and another one.
Since english isn't my native language I can't deciphre the last one (contains the letters t o s e o r h). If anyone can help me I will greatly appreciate it.
