The written numbers don’t match in the tip line and total line, I bet the waitress sucked so they left “0” tip and the poor little queer decided to punish them with an falsehood.
It’s not uncommon to pay with a credit card but leave a cash tip on the table. I do it all the time.
This stinks to high heaven of HOAX!
1) The receipt looks like the customer copy, not the merchant copy.
2) The writing not only doesn’t match, it looks like it’s “floating” on top of the image by photoshop.
