Imagine this if you will. A young lad who is very keen having done level 1 at 16 now with his sgc gets permission from an land owner (and family friend) to shoot in a few specific fields for vermin, mainly pigeons but rabbits too. He doesn't shoot in any of the woodland and is very grateful for what he has, helping out on the ground with harvest or whatever needs done.
On the other side of things a guy has the deer shooting rights and basically claims absolute supremecy and thinks all other ground users may only do so with his permission and at times he allows. A run in occurs through a third person and basically the young lad is strongly warned off shooting the ground because this other guy paid for the rights over it and pigeon shooting is not necessary now the crop has been harvested so he doesn't need to be there.
The owner of the land hears about this and in a nutshell tells the lad to carry on whenever he feels like it on the fields agreed and says some interesting things. So the warning is simple. Don't think just because you have paid for deer shooting rights that you are in charge of the ground by your rules. The land owner might quickly decide your not the type of stalker he wants there. Be nice and get on with people even if you have to put up with someone else shooting vermin on your deer permission because they might be far closer to the land owner than you.
One guy today just pis5ed on his chips.
