I was watching a video from two years ago about different social norms and this showed up. Found someone questioning the same eight years ago on reddit (when it seemed less normalized). It feels so weird not being aware of this shift, even as a foreigner.
That’s interesting, as a British English speaker “your welcome” to my ear sounds quite American - that may be just me. I’d be more likely to say “no problem”, “no worries”, or “don’t worry about it”.
