YOU KNOW WHY THEY LEFT OUT JAPAN...

The Reader's Digest Global Courtesy Test, which ranks 35 world cities by degree of politeness (though suspiciously, their own article talks only about NYC), is certainly rankling some major metropolises, who feel they've been underrated, and are being rather unpolite about it; others, like No. 1 NYC (where many are saluting with a different finger today) are surprised and flattered, though the test is admittedly unscientific, so there's still some rudity wiggle room here. As to entire land masses, Asia turned out to be the rudest continent.

Less polite cities

I noticed right away that the surveyors left Japan out of the picture altogether, likely because the entire country is so courteous it would skew the test right off the page.
