Eve Incident, which refers to a true event happened just yesterday, caused three of us been locked in the meeting room for quite a few minutes. Normally, the room can be freely accessed without scanning a badge, but it was locked up while we were having a short discussion in the early hour of that morning. What was worst is that none of our badges was working on the scanner; not even our admin's. As a consequence, colleagues outside the room were amused by our confinement. Later, when we were finally "released", we learnt that our security department had a system upgrade during the previous night. They, somehow, foresaw this short of incident to happen.

At the bottom, beside the door, there is an emergency swicth, which was what they were looking at. But we just waited and didn't do anything obstrusive.
