Wait, how comes on the fifth map, "McDonald’s Across the World", Iceland is shown as not having McDonald's, but at the same time it's listed as the third most expensive country for McDonald's burgers?
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.
