If the guy won the chips over several sessions...
... like winning a $1000 before quitting play and getting colored up then walks, does this say 4 times over a week long vacation. None of the $1000 wins trigger a Title 31, by itself. Guy leaves, comes back months or so in the future. Cashing in the 4 $1000 chips trigger a Title 31 (cash out), BUT the casino now requires PROOF that they are yours from a win?
Is it illegal for me to give you chips I won for you to cash?
This is getting MORE confusing!
