Thanks for bringing that topic, for me as an expat it a major pain. I live in a country with rather unusual language, but I have only contact with English speaking people. And every service puts the locale of this in default - even with stating in browser settings what are my preferences.
The worst part of this is that in many places I don't even know how to change local on specific pages manually.
VPN is the only valuable option for me unfortunately.
