Stupid customer - "Hi, yeah I was just there at your branch a few minutes ago"

***silence***

Me - "Ok...and how could I help you?"

Stupid Customer - "I think I left something there. What can I do?"

***silence***

Me - "Um...you could come back and get it?"

Stupid Customer - "Oh ok, thanks"

Um....wtf???
I'm thinking it was her brain that she left behind.
Dipsh*t.
