If I had a nickel for every time a client claimed that they already brought a document to me, and they actually didn't... well, I'd a have a metric shit-ton of nickels. "It was in the packet I sent you!" .... well, buddy, I'm looking at the contents of that packet and I'm telling you, it's NOT HERE. .. Commence client bitching and moaning for me to look harder and weeks later, them finding it and then lying and saying, "I found a copy of it so I'll send it to you again, but YOU have the original"... only to get the document and plainly see that it's the original. FFS.
