Oh my goodness! Crazy stuff! At least you got your awesome chainsaw out of the deal.
My daughter, 14 at the time, listed a fireplace insert (the kind you plug in and it looks and sounds like a fire) on a Facebook group. We went to meet the man and apparently he had seen a post of hers with her picture and thought he'd try something. I handed him the fireplace thing and asked my daughter to get back in the truck. I said "You have a choice. You can pay your money and drive off while my daughter takes a picture of your truck and tag. Or my friend over there, Deputy Ferguson in the squad car parked under the tree gets to take a picture of you for your mug shot." He handed me a 100 and took off. The thing was only 30 bucks and I actually have no idea who was in the squad car Lol. (I only had a machete on me, too messy if I had needed it. Glad you got your CCW)
If needs must, a man (or woman) with no horse may let go forth on his own feet :) I'm sure that machete would have served you well had there been need of it!
