This always baffled me. Although English is not my native language I strongly dislike UIs being in any language but English. Every settings on my PCs says use English, all the apps are English versions, yet every time I find myself in another country Google uses its language to speak to me. I'm not sure I will even find how to switch the language to anything readable once I land in e.g. Japan or Armenia...
