Hide.

Seeing as you are filthy and smell of sex and mud you duck behind the unused clothes rack and hide till the place closes. Finally alone you come out quietly and look around the place to be sure no one is here. Satisfied you strip naked and take a long hot shower. While you get refreshed you think over your options:
Steal some clothes and money and break out. Do the same but wait till the club opens hiddin and slip out in the crowd so you don't set off some alarm. Or does someone find you?
