I think they appreceate the gesture more than the gift itself sometimes, as has allready been said, where else would you get value for money like that ?????. Apart from that, its good manners and courtesy on our part to show that gesture for permission. You'd have to do something pretty f****n stupid to be chucked off permission by a farmer that you have built up a good rapport with, more so if you are in his wifes good books lol. Its all about respect, manners and gratitude, very simple qualities to nurture and use, but all to rare nowadays.
