Just in case someone is actually confused: I am sure you can buy McDonald's-equivalent burgers in Iceland or at least estimate the cost of a burger if it were to be sold there (in the appropriate quantity typical of such a country etc.).
Well, they do say "McDonald's burger" not "equivalent".
Give what ronaldx said, I suppose it's a case of using different dated data for each part of the map, but this doesn't look good, someone should have catched that before publishing.
