what is a good roi for a bettor?

[sumitas]

That's about it. I get to stand in line waiting to place my $2 wager. But I get to hear Mr. Bigshot brag loudly about his upcoming Lobster Bake at his lakeside retreat after he returns from a coast to coast business trip and how he's gonna bet $50 or $100 on a horse on the upcoming race because he looks so good to his eye.

after the race i cash my ticket and chuckle Mr. Bigshot is outta his bet; if we're not both outta ours.
