I was just in Bordeaux. Not a single issue with my weak French and I’d almost always get a reply in French. I promise I am nowhere near fluent, maybe A2 level. But in Paris, nearly every reply was in English and even if I replied back in French I’d get that look “please stop butchering my language” before they’d reply in English. It’s a running joke now, but I really question if it’s just parisons being assholes or maybe they just want to practice. Ps. Never had this issue with Italian. My accent is almost Roman too and I’m again, not fluent.
