Finding the manager's office was a simple enough task. In fact, with the corridor you were in heading directly to the center of the tower with no twists or turns, it was well in view in no time at all. It wasn't anything fancy, admittedly - a simple booth tucked in between the six elevator shafts on either side of it, with stairwells behind it leading up and down. The front of the office had a big, clear window with a small port for exchanging items at the bottom, as well as a mic/speaker at about face-level. The lights inside the office were off, but with the light from the central chamber filtering in, you could make out two desks, one with a computer terminal sitting on it, as well as a bunch of file lockers, a water cooler and a vending machine. To the right of the window was a simple sliding door with a panel next to it.
There was just the one catch. The door panel looked like a security card reader.
