I was trading an old sword that I had for a mossberg 590 once, and the deal was that I would put some cash on top of the sword to even out the trade.
We shook hands, and I got a receipt from the shop manager.
A couple of days later the store owner calls me and says that a "sword expert" looked over my sword and told him that it wasn't good blablablabal and that I'd need to come in to renegotiate the trade.
Well, I go in and have a chat with the guy, and after listening to him ramble on for a few minutes it was clear that no one had come in to look at the sword.
In fact, most of what he was saying was old wive's tales and misconceptions.
He couldn't keep his story straight and mentioned that his source was the Ebay "how to grade a sword" web page.
I was pretty P.O.'d but I just kept quiet for about 20 minutes while this guy went on and on.
I'd had enough after he showed me a "damascus" steel knife to point out how the laminated steel on my sword looked nothing like it. This was proof to him that my sword was of low quality. Ugh.:banghead:
I then, in about 3 minutes, responded to his 1/2 hour spiel and corrected him on the more ridiculous points he'd made.
As a punctuation mark I told him, "and I've got a receipt, so frankly, I don't know what the point of this conversation is."
He said "ok, that's binding I guess" and shook my hand without looking at me before storming to the back room.
Honestly, I was willing to renegotiate since I was coming out on top with this trade (the sword needed restoration), but when the guy lied to my face and tried to stick it to me like that I lost my willingness to make it more favorable for him.
