Where (not) to Place Builder Huts

I have never understood why people place their builder huts in the corner of their maps. I have never ever run out of time when trying to three-star a base because of a builder hut in a corner (and i am currently a level 107, so i have played a lot of matches). In fact, whenever I am ninjating for cups, I love it when someone has builder huts in the corners because I can pick up some easy percentage with only a couple of archers. Don't do it.
