Chocolate,
This is an assignment to me. Kilwa road, is the road which I always used to reach home but I never ever seen such electricity posts. If your observation is correct, its unfair to put one post at mtoni kwa azizi ali and another at mtoni mtongani (darajani). I doubt, may be you have seen something else not electricity posts. Even if is 'fundi mchundo' no one can plan in that way coz the purpose of having electricity posts along the road is to have light, that, users of the road be able to see clearly every objects rolling in the road.
