The problem is such look like a safe bet when in fact not... I have seen people lose on a 1.005 odd bet which looked like a sure bet but turned out to be a high risk bet that will lead to losing and the unfortunate thing about such wagers is that a player needs to put in alot of money to have a small profit but in the end its all burst! Btw I think bookies actually make more money on such bets because of our greed, it's a hard lesson learnt and can never be too sure of an outcome.
