Oh & do you see the manager come out and open the back door to walk to the back?
One time, the manager went into his office, and never came out again. The other time, he walked into the freezer and got a trash bag, then stayed in front of the freezer looking at me.
I wondered if maybe he's not completing his AI script, and the wall is to prevent me from interrupting it or something. I hope my description helps you! :)
