One cashier and one cook. The place was understaffed. Regardless they shouldve sat that group of 25. Black, white, whatever. Seat them and. serve them. Even if it takes three hours.
That employee that refused them service may not have been racist, but he sure was stupid. Very stupid. He shouldve seen this coming. Stevie Wonder couldve seen this coming. You gave blacks the special attention they demand or you will pay for it.
One of my first jobs was working in a Waffle House clone and was the only worker there on 2nd shift when a tour bus with 30 people piled in the door.
Waiter/cook/cashier and dishwasher, I had them all in and out of there in an hour.
