I am not going to call it a hoax out of hand. I WILL say that the note looks like it was written by a woman.
I'm absolutely calling it a hoax. I demand that this waitress straight-up PROVE that a customer wrote this note. I think that's impossible to prove. So we are that the Fake News stage, the "some folks say" that a customer wrote the note stage. I no longer accept such crap. Lacking rock-solid proof, I call this a hoax and I encourage her to shut up and go away. I no longer sanction this crap. I will not be a victim of the race hustlers.
If it’s not a hoax, it’s not worthy of media attention. There will always be screwballs. This unworthy report only stirs up hatred.
