Some of the reasons they cited that it is fake are kind of questionable in my opinion, not all, but some. Don't get me wrong, I kinda lean to it being fake as well, but the stamp just looked like a bad stamp to me, not "hand drawn". The example of a proper stamp on the first page even has a weak stamp next to the good one, so it's not unreasonable to say that whoever stamped OP's said "meh, good enough". Another thing is that the Fender Custom Shop will seriously make just about anything you ask them to as long as you're will to pay for it, that covers a few of the other explanations on why it is "fake". I could go on and on, bottom line is OP was never all that rude considering how he was treated, and if you pay attention to some of these guys that replied you can see that many have a knack for coming of as insulting and getting into arguments here on TB.
