Did they respond differently depending on what race they thought you were? I'm surprised they would even do that honestly. I thought they were trained on text conversations which presumably wouldn't have any of that to learn from.
For French people like me, false friends are immediately noticeable: for instance, "actually" to mean "now" instead of "in fact".

I will elide the rant inside me that west coast 20 somethings get to decide if speaking in a certain accent is racist or "bad". But it's a heartfelt rant.
