We've all had it happen before, we see a bad line and make a large bet on it. When the books discover it they cancel the bet. This has happened with live lines and the bets being cancelled after the game is finished.
Should books be allowed to do this?
My answer is NO they should not be allowed to cancel bets, especially when they don't realize the error until after the game is finished. I have made the odd mistake when placing bets (taking the wrong side, a zero misplaced etc.) I have written the book and told them my mistake but they have said, "you hit the confirm button' and should have double checked. They are correct, I made a mistake and have to live with it so the double standard is incorrect in my eyes.
