Power crisis

These days I am extremely busy in a project called sandesha2 and I have to finish it before I leave SL - which makes me to work round the clock.
This morning I woke up to finish the major coding part and worked happily until 8.30 a.m. Suddenly the fan went off along with my ADSL router - a power cut !!!!. At that moment it was actually a good thing because I could take some rest.
So I went downstirs and started washing some of the clothes. I took a little nap, read a little bit of book ... but no sign of power ... So finally about 1 p.m (yes, I waited that long) I called the local electricity branch. Answer was simple - you won't get power till 5 p.m. Okay .....
So I packed up the laptop and headed for my office hoping there won't be any power cuts at the office. The travel took around 45 mins .. and it was around 2.30 p.m when I reached there. So I worked till 7 p.m and came home ... luckily electricity was there .. But overall waste of time is more than 3 hrs. So my question is: Aren't they polite enought to give prior notice about the power cut (mind you .. this is a highly industrial area and a power cut means a total loss and the power cut lasted almost 10 hrs) ?
