1)"We don't serve Negros." "Good, 'cause I don't eat them."
3)"You're not Banksy!" "Or am I?"
4)"I don't recognize anyone by that description."
5)"We're not harboring anyone who has no right to be here."
7)"I did not warm to him."
8)I was interested Yaz and Ryan's conversation while they were hiding out, that the writers didn't gloss over that there's racism in contemporary Britain.
9)"We have to not help her."
Overall: I liked this, It can be tricky when they bring in real world characters, especially as this is probably the most intense look at real world racism the series has ever done. You felt more worried for Yaz and particularly Ryan than you would have had they been up against Cybermen or Daleks.
