Remember, if someone is speaking English to you with an accent, they are probably, by default, smarter than you because they speak two languages. Don't patronize them.
@Miriamm I used to have an unconscious bias against heavy accents (being multilingual myself, but have little-to-no Dutch accent when I speak English). I didn't realise it until I moved to here, and it took me a while to really lose that toxic part of myself.
