The man she was set out to win the favor of didn't seem to be paying her any mind, but the other players, none of whom were nearly as invested in the game anyway, were easily distracted by her 'charms', and soon he'd start winning - not a lot, but enough that he seemed to be relaxing a little, even if he was still fully focused on the game, and not her. Sophie did her best to do the job, not really seducing the customers as much, and didn't get nearly as much attention as Delphine did.
