Waitress (Rosa)
From Tardis Wiki, the free Doctor Who reference
This waitress worked at Slim's Diner in Montgomery, Alabama in 1955.
She noticed the Thirteenth Doctor and her companions Ryan Sinclair, Yasmin Khan and Graham O'Brien in the diner. She approached them and said that they did not serve 'Necros' (referring to Ryan) or 'Mexicans' (referring to Yasmin). Ryan flippantly responded, "That’s alright, I don't eat them", to which the waitress told the group that they would have to eat somewhere else. Following this, the Doctor and her companions left.
