What Happened to the Lights?

Today I got to home from work early. No, I wasn't sick or injured. The simple explanation was the power went out. It didn't just go out where I work but all of the city went black. It's a good thing that it was still daylight. As I was just finished helping my one and only customer and creating a receipt for her, the lights flickered. The computer rebooted so I decided to finish creating the receipt only to experience that the computer I switched to froze. I was a bit dumbfounded as what to do because we lost our network connection. I ended up writing out a receipt for my customer. After I finished with my customer, the lights went out. My co-workers and I closed up shop because we couldn't and didn't want to help anymore customers. So needless to say, we went home around 3pm. It was a glorious day considering CarbonMan and I were up at 4am (even though I went back to bed and slept until 7am when Gary started meowing outside the bedroom door) so that he could catch his flight for his business trip.
