Before anything else, readers need to know that they should never bring money to the casino that they might need for basic expenses like the utilities and the rent. That would simply be ill-advised and you will only be giving yourself a real headache.
Remember, gambling should be seen as a leisurely activity. It is something to do when you have money to burn. If you feel that the money you have now is something you cannot afford to lose, then do not go to the casino.
