I once accidentally spoke french to a waitress in Greece then apologised and said I wasn't actually french. She went on a ten minute diatribe about how french people are the bane of her life because they refuse to speak English with her and just get louder and louder in french 😂
It's like the Canadians when they don't want people to think they're Americans. Some Americans even pretend they're Canadian for the same reason. I'm French and I knew about these for a long time but never thought of the parallel with France/Belgium. Damn I might start using this and just say I'm Belgian haha.
