My first indicator something was off was that when I showed up the dude walked up to me and was open carrying. Sure, it's his property and all, but it's not the best way to greet a total stranger coming to buy something from you. It definitely put me on the defensive and wary immediately.
Damn, I didn't realize it was on this level. I would have saved the trip had I known, but I was just out some fuel and time. At least I was able to stop by the Gainesville for a bit. It's another reminder when dealing with a new seller to always see the thing and test it first before exchanging cash.
