I thought it was her brother's staff at his restaurant?
Although this is what I find hilarious, if she had gotten that Plantation themed restaurant off the ground with a completely black waitstaff in period costume... Odds are that the staff would only be completely black at the expense of a number of lawsuits about unfair hiring practices, because rationally your Asians, Native Americans, Whites and even Mexicans would be arguing that they can be just as good House #####s as an African American... I mean, sincerely do you believe that all the waiters at Long John Silvers are authentic Pirates who raped and pillaged the seven seas? And if you did believe that that was so, then you should've already called interpol to report these scurvy maniacs for crimes against humanity.
