I have learned to spot them before they spot me. And if I am talking to them and I see they are not getting it I leave abruptly. Little example. I am out in the woods hunting and this guy stops me on the road and asks me where he is. I start telling him and he starts arguing with me. He is the one who is lost asking me where to go and he is arguing with me. I tell him to have a nice day and next time he should buy a map before he goes out into the woods. I drive off ending the conversation.
