It may be because the French are simply mirroring the haughty attitude of their former president Jacques Chirac (pictured) who is said to be the only man in Europe to need suntan lotion on the underside of his nose.

Given their nation's long reign as the world's most visited country, you'd expect the French to know a thing or two about insufferable tourists.

Affirmation-starved France usually loves global titles of any kind (one big reason French competitors tend to outnumber foreign rivals in quixotic contests like reverse round-the-world solo yachting races and France's annual international plumb-spitting tournaments).
Reverse round-the-world solo yachting races indeed.
