McDonalds is only "home" for Americans. As the parent comment says, it's "consistent", but it's absolutely not "home" for me or anyone else I know from Europe. And for anyone who has tried McDonalds on a few different continents, it's not even that "consistent" in what you can expect, I think people are more interested in the consistency of safety, i.e. you have a lower risk of being food poisoned than you may have from some of the other establishments nearby.
