This is easier to understand when you actually understand what the tipping law is. That tips may act as a credit towards an employee's wage (up to a max that's < 100%). How is the credit calculated? Besides video, the only hard proof is by whatever you write on that receipt.

So like you, I carry cash for tipping. I leave the tip section blank and write the provided total in the "total" line. Then I leave cash. Employee gets to decide if they declare or not (or in other words, if my tip may be credited towards their wage).
