Serious Question!

Since most of us don't have the P word tattooed on our foreheads anymore and the Scarlet "A" is out of style now (lol), I am interested in what makes you think/know that she was a provider.  

I always dress discreetly, avoid anything beyond polite eye contact or nod in an elevator, and use old room keys to breeze past security yet I still sometimes I feel like as a pretty girl walking alone through the casino or getting into an elevator by myself maybe strangers can guess my secret.  

So how did you know?

Oh and PS did you ever find her!
