Sara,
Do you have absolute "Proof" on what you are thinking? (3 versus 2 employees?)
What is in your notes when you left the shop? You did make notes right after the shop, correct? Also, did you record the shop (as in using a DVR) if you live in a 1-party state? Go back through your recording.
I would tend to say that you are over-thinking and arguing with yourself.
