At my old job, working in Architect firm and I was a manager of CAD dept plus IT. One day we had an power outage for a very short time. Everything seem to be ok and the server have no interruption. Then later, one guy waved at me saying that he couldn't get a file off of the server. I checked and truely enough that I couldn't get on the server. So, I went to the server room and found out that the UPS (Uninterruptable power supply) didn't switched back to normal electric instead of running on battery. The server was completely shut down. You know, there's something wrong with switching system. So, I decided to move all the plugs off of UPS to power strip.
Suddenly, saw my boss who is partner of the company, walking toward the server room (see him through the glasses door), and he opened and took a peek through the opening of the door and said:
"Do you know what you are doing?"
Me (puzzled, and holding the three prong power plug): "No, I never seen this plug before, where this go?? What this do?"
Boss dropped his head so low, facepalmed. Then he closed the door walking away with his head shaking....
I was hoping that I made him more nervous...
Me thinking..that was the stupiest question he ever asked me.
