So a few months ago this black guy comes into my store to sell some games and movies. They were in pretty rough shape but I thought they were repairable (though barely) so I did the polite thing and give him full cash trade-in value as opposed to the usual low value for such low quality items. I smiled, gave him cash rounded up to the nearest half dollar, handed him the receipt to sign for our paperwork, then he walked away w/o returning my farewell when I noticed that instead of his signature, he wrote "eat shit, cracka" on the dotted line.
Why. The. Hell? I have no idea. I was polite, generous on the trade-in, and again when it came to the payout. What sort of reaction was he hoping to get after my openhandedness is spat upon? Was he trying to make me hate him so he could feel justified in his own little racist world?
And to top it all off, under the massive scratches the games were all cracked and dented.
So "fine" I figured. I went into his account info and typed "do not accept trades" in the Notes header.
So I guess the prick succeeded.
