What I should have explained is this.

Technically they have bet me the fixed odds of $9.00.

Also they have let me on for the rest of my bet.

So they have fulfilled both obligations haven't they?
But in a round about way that if invoked this rule,
Of betting all punters the price on offer to lose a set amount,
Would have to be re-worded in this scenario.

Bet all punters to lose a set amount at the fixed odds displayed,
For the "EXACT" amount the punter asks for providing that amount,
IS NOT EXCEEDED RE THE RULES GOVERNING THAT PRICE
AND RULE PERTAINING TO WHERE THE MEETING IS HELD.

Cheers.
