Eguller 'Waste Areas'.
It all depends on what the 'waste' is, in those areas. Would you hit your brand new irons from that spot?
Rocks/stones have no place on a golf course, except for parking lots/banks of ponds. Here, they use them for bunker 'fill', apparently. And, people actually do hit from them, digging deep, throwing all of it up on the greens. I shake my head when I see all the stones embedded in the greens, then wonder what that club now looks like.
