Customer cons

A woman came up to me at the theatre and asked, "Do you have a lost & found here?'
I nodded.  "Yes."
"Did anyone turn in something small?" She held her hands up in a vaguely rectangular shape.
I waited for her to finish, but it seemed that was all she was going to say.  "Like...?" I prompted.
She hesitated for a second before answering.  "Like a wallet or a purse?"
I shook my head.  "I don't think anything's been found recently, but I can go check.  What did it look like?"
Another long second passed while she considered her answer.  "Black?"
"...okay."  It was kind of busy, so I'd been running on automatic and hadn't really been giving the situation much thought.  This was enough to kick-start my suspicious nature though, so I stopped and aksed, "What's your name?"
"Oh, it's not mine.  My friend lost it and wanted me to ask about it."
I waited another moment before asking, "And their name was...?"
"Judy?"
In the office I did a token search, and wasn't surprised that there wasn't anything belonging to someone named Judy.
Behind me, she must have heard me digging through the lost & found box and recognized the sound of the many pairs of sunglasses that had been found.  "Oh, my son lost his sunglasses here last week too."
I turned around, careful to keep the box out of sight.  "What did they look like?"
"I don't really remember, could I just-?" She tried to look past me into the box.
By then I was getting tired of her wasting my time and I started herding her out of the office.  "No, sorry.  He'll have to come in and get them himself."
She gave me a final glare and stormed off.  It was about ten minutes later that she found me again, tearing tickets.  "What about cash?  Did anybody turn in any cash?"
I didn't answer, and just looked at her.  It was one of those statements that took my brain a couple of seconds to fully process.  Did I hear that right?  After all that did she really just ask for any cash that might be laying around in the lost & found?  How stupid was she and how stupid did she think I was?  She must have read the expression on my face and guessed what I was thinking, because she didn't wait for an answer and left.
