I don't know how much of this was in jest, but I had something like this happen at my place with a guy that I allowed to deer hunt my land. Long story short, he didn't get a deer and when I was next on property, I found one of my LARGE oaks next to my gun range had a target on it and 20-30 rounds shot into the target and tree. I call up my buddy and asked if he did any shooting while "deer hunting" and he explained that he needed to sight in his rifle so he put a target on one of my trees. When I asked why he didn't use my targets on my gun range (400 yard rifle range with tables at 50, 100, 200, 300, and 400 yards), he said because he hadn't asked permission to use my range. Well, he didn't ask permission about shooting up a tree that is probably over 100 years old AND he did use my rifle range, one of the shooting tables from which he shot the tree. He didn't even bother taking his target from my tree. Needless to say, he won't ever be on my property again.
There are people out there, pretty much like you explained and I experienced.
The point is that your little story isn't far from what I have experienced.
