I blame Bob Vila for most of this...
His idea of electricity is to just find somewhere where there is power and "tap off" to feed something else.
In my experience, anytime that something sounds simple generally isn't.
Besides, little loads tend to get bigger as the design progresses. The little water cooler suddenly gets some new friends like a pop machine, candy machine, then someone wants ice cream, ad infinitum, ad nauseum.
I would suggest that the 'tap the nearest power' idea get deep sixed; and the little building fed the right way (with its own feeder/branch circuit(s)).
