Provided she stuck to white wine there was no risk of staining, she could take it back no questions asked. Of course she'd bite the bullet on the price if she had to chase down any slime balls who knew where Ricadonna was. She had a pistol strapped to her inner thigh loaded in case of a fight.
She may not have been the New York socialite that Danny wanted to rub shoulders with but he had definitely bumped into it. Her glass of champagne jumped out of her glass but managed to miss her dress.
