Dude. That happened to me before as well. Not the same guy though.
I walked away with my stuff the moment the chap asked for a further discount.
Your friend should have done the same, or at least stood firm to the $240 asking price. Seriously. Letting such people get away with good deals is a strict
no-no.
C'mon. Your friend clearly knew the chap had more cash on him than he claimed he had. So why back down. You're the one with the goods, he's the interested party.
I hope I meet this Bronson.
