I would have laughed, Cause i've done it and didn't get it back. Personally its a video game if someone wants to give it back good for you. If not well sucks to be you but OH WELL... its not the end of the world
Good hearted yes, but saying that honesty would be negated because someone wouldnt give you gil back after your negligent purchase would be incorrect. The liability rests on the negligent party, and the individual that chose weather to or not to give back gil would remain just as honest either way. There was not trickery here.
Not too long ago i found an l. jade in a guy's bazaar for 10.5k, so like anybody else i purchased it. Shortly after he was mad. Moral of the story, don't screw up. Also if you do, don't ask for the money back, learn from your mistakes.
I have sent gil back before the person even caught me online before. I would hope someone would be willing to give my gil back if I make a mistake, so I just do the same for others.
