I can't speak for what occurs at other casinos, but when I pay your taxable (if it's under $5,000), I send the amount through, I get all your info, I go to the computer/jackpot terminal and enter all your info, and print the jackpot ticket and the W2-G. I then return to your machine and pay you. The only thing done in any office is when they later check to make sure I didn't mess anything up, and if I did, I am the one who is punished. That being said, there are generous people and there are not-so generous people, and I accept your decision as to whether or not you tip and how much you tip.
