Failure to do so will result in the denial of the application and denied entry into any of the EU countries.

So, if some boorish individual doesn't pay the proper respect to French embassy officials, they'll be denied entry to any of the EU countries? According to what I heard this morning, the French version of the sign says the ban will be permanent.

Look, being rude to the Embassy officials is wrong. However, if they're as arrogant as French waiters, perhaps some people are reflecting that attitude back at them. What gives France the right or authority to ban someone for over 20 countries? Talk about Gall!
