Entitled wanker is exactly how I'd classify this one. On top of seeing nothing of making an entitled demand on her friend's "gift," and of the effort for the woman working for them, I think the friend not seeing the cultural importance this language plan has for the LW, as well as her thinking it should be no big deal to require a Spanish as first language speaker to speak in English falls under the heading of aversive racism. Maybe LW should encourage her nanny to ask for more than a "small premium" of her friend who she has allowed to DOUBLE the nanny's work load for longer than was initially anticipated because her labor is really not the LW's "gift" to give, ya know? The friend is an entitled wanker, but both she and the LW are treating an employee like an exchangeable commodity here. Pay her the fuck more.
