Dont get builders like this in the uk

Posted this before, but videos reminded me of it, was over in Tenerife, there's a guy painting a six story apartment, he's got a shash clamp clamped to the top balcony wall, at the end of it there's a pulley through which is a rope attached to a sling chair, the guy paints what he can then lowers himself down a bit, and then paints more, but to get maximum efficiency out of each hight change he swings from side to side to get maximum spread with the paint...
