You knew it going in that the odds of winning are stacked against you!!! Winning is the exception to the rule! Have fun. If you win, great! If you lose, don't cry. If, however, that $100.00 bill is earmarked to pay for groceries or rent or utilities or other obligations, don't even think about going to a casino! Go to a casino for entertainment and fun and stick to your budgeted bankroll! Budget an amount you can afford to lose.
Here's the bottom line: If you can afford to take a $100.00 bill out of your wallet or purse, strike a match and burn it without bothering you at all, then go to a casino.
