In all seriousness though, I think I have only seen this as an issue when it's a place written outside the USA, but it's written by someone that lives in the USA, but the author has NEVER BEEN to the country to they are writing about, with their only research on the country being either 'none' or 'popular media'
There was a HUGE rise in that when manga and anime became popular. Lots of people writing stories that took place in Japan without actually living in Japan and only knowing what they know about Japan from Anime. And you would get this really really weird cross culture confusion from American ideologies, social norms and idioms being thrown around in a Japanese setting that just didn't make sense????
