After about the third time I genuinely thought about taking my shotgun down to the creek to "discuss" what they were doing. Then I thought what if I get put in a position where I have to use it? What do I do with their car? Will someone miss this person and come looking? I was also not sure my dead body hiding spot had room.
So I decided on a bat, which sometimes leaves me out gunned as most of the time these blokes have a pick and shovel. So I always use the element of suprise to give me the upper hand.
