Maybe I am assuming a lot of things here but is this your experience with businesses or people in the streets ?
In France we have a totally different approach than Americans for exemple regarding people we don’t know. Even between french speakers we will generally not be light chatting with strangers (exacerbated in dense populated areas like Paris/Lyon), as opposed (as I understand) to Americans who can talk to anyone anywhere.
I often wonder if this sentiment of disdain for English speakers is not due to this misunderstanding of our habits.
