During my last session, I left my keys in her office. I was paying for my session and when I was done, realized that I didn't have them. So I asked the receptionist to please go to her office and grab them for me but she had already found them and given them to receptionist number two. Wasn't a big deal though. First time I ever left anything there as I usually have a random few moments to gather my things while she writes out the payment slip at the end.
