If you wager on the New York Yankees +300 vs the Detroit Tigers at a sports book knowing they made a mistake and meant to type in -300 instead would you feel entitled to demand that they honor that wager if they notify you of the error before the game starts? If you tried to argue yes on any sports gambling forum you would be (rightfully) laughed off and called a crook by every single poster on that forum.
I can understand why you wouldn't want to answer this question. It blows your argument right out of the water. Stick to baseless accusations that I'm "casino staff" because it's all you have to hang your hat on.
