Covert Racism Restaurant Employees

Something I noticed here in Pensacola. I've been hearing about the covert racism in downtown Pensacola, ever since I moved here. + experienced it, myself. 

Why are the Black restaurant employees usually the ones to do back of house (BOH) slave cooking & cleaning (to be unseen), while the White employees get to do front of house (FOH), & they get DAMN good tips? 

& they'll put in 1 Black female hostess at FOH, to try to not let their racism look so obvious.

Usually the servers (waiters/waitresses) & hosts/hostesses are White employees. 

The dishwashers & janitors are mainly Black people.

Sometimes, the line cooks could be either race.
