Unlike Blackie's ripoff joint, BI's rounding works to the bettor's advantage too. For example, if you bet $50 on Houston +155 today, instead of potentially winning $77.50, your win amount is $78. So your claim of BI making extra nickels and dimes is absurd. It works both ways, and all you have to do is adjust your bet to avoid being on the wrong side of the rounding.
