I remember my dad when brought me to a Casino in Cebu and all the winnings that we have are all accounted and never mixed with the regular money that we have. We bought food, we use it pay the hotel bill, buy some local items to bring home, but never put it together with the money that never came from gambling example put is inside the same wallet, my dad says its bad luck, literally its like dirty money, he set it aside from the clean ones.
