The Dare

You are Frederick Davies and you have been studying hard for a degree in law. The examinations are now over and it is Friday night, so you and your friends decide to "let down your hair" and go out for a "night on the town" to celebrate the end of the examinations. So you set off for "The Swan" pub and after a heavy drinking session you are dared to try to get out of a large department store in town after it has closed. Somehow you are talked into it and your so-called "friends" have taken all of your clothes and left you locked in a toilet with nothing but your underwear. You were pushed into the toilet just before closing time, but as you were pushed in your hit your head and have been unconscious for some time. You wake up, everything is blurry, you aren't sure how long you have been there and everything is very quiet outside.

Can you get out of the store without setting off any alarms or alerting the police or the security guard to your presence? It would be most unfortunate if you were to be caught, as it would most certainly end your career in law before it had even begun.
