I’ve never met someone from France like that either. The one man I personally knew was a scientist I worked with in a summer job years ago. When he found out I spoke French, he treated me very well. Everyone else, he treated like garbage.
I just remeber the two who kept pushing in line at disneyworld. Rude & didn’t look like that either.
I feel the rudeness is the physical manifestation of the frustration brought out by the accent that develops when one speaks French primarily. Sort of a complex, rather.
