well, what happens when you stumble across a set of really awesome wheels with nice rubber and they're a killer deal but you gotta buy 'em right meow, and you don't know if they fit
I was selling parts to an F100. A guy came over and wanted to buy stuff. He wanted to buy the wheels, but he wasn't sure they would fit. I told him to take one home and check it out then come back and buy the rest.
He said he was sure they would fit so he bought them and a bunch of other stuf. He wanted a discount for buying so much.
Well am hour later he was back wanting his money back for the wheels cause they didn't fit.
I was selling the wheels for 75.00 each and then with everything he bought and the discount on the total that brought each wheel down to 50 each. So that's how much I was willing to give him back. He was not having anything to do with that and demanded (by threatening force) that I give him 75 per wheel back.
Well my wife (gotta love her) was listening to the exchange from inside the house and came out with a baseball bat instead of calling the police, So i gave him 75 per wheel and sent him on his way. I knew where he lived and I relived my planned revenge in my head for years, but I grew up a bit and didn't do anything.
Edit. I gave him the 75 per wheel not 25 per week back. Cut my losses.
