Have you ever ran a book? Have you ever sat in a gaming ops meeting when they are discussing revenues from each department? If you can't answer yes to either, kindly shut the fuk up. Public plays are usually the same plays that fill up the sucker bet parlay and teaser cards so it is always in the casinos best interest for the public to lose. The business is always going to thrive. Sports bettors come and go. They don't give 2 shits if some jerkoff like you goes on a hot streak betting heavy favorites. A day or two of the popular faves getting beat and you are gone and another schmuck takes your place. Horses are what keep the books afloat with the guaranteed %.
Here is an example of how the books take public money: Yesterday Hammels was somewhere in the -240 range. About 90% of the public backed him ml and rl yet number dropped a little. 2 reasons, big money was on Houston and they wanted more public Philly action. Hammels gets lit up and people like you get wiped out.
