Maybe this is a specifically English thing, and not an issue in your native language (assuming you're not a native English speaker), but the idea of putting on an accent carries a LOT of baggage. I think it happens to the extent that people will sometimes tailor/'round off' their accent and vocabulary depending on context. But people are attached to their accents - it's part of who they are - and having to put on somebody else's accent in certain contexts is not something that most people would be okay with. The idea that, for example, I would affect a, say, American accent if I was making YT videos, is completely crazy. Let alone in everyday life.
