Why does the Government allow this, but then say "if you have a problem gambling call this number"? If you have no chance from the beginning, what's the point?

Legislation needs to be put in place whereby a Bookmaker must take on every customer to a certain liability each race/sporting event, regardless of whether they're positive or negative overall. The TAB used to take customers on but have recently decided they want even more profit so they ban/limit anyone that wins. Corporate greed at it's finest. There are an extremely small number left that still do this (and are probably getting increasing business as a result).

If their business model can't incorporate this then they have no place in the business of bookmaking.
