Bravo Star Geneva Thomas -- Justice is Fare in Cabbie-Stiffing Case

"Blood, Sweat and Heels" cast member Geneva Thomas will shell out $18 the next time she jumps in a cab ... because her penalty is keeping her nose clean for the next 6 months ... OR ELSE!

We broke the story ... Thomas was busted back in September after cops said she skipped out on an $18 cab fare. Now a deal has been struck ... if she stays out of trouble until July ... the case will go away ... as if it never happened.
