I'm French, and I find it pretty easy to believe. I even have another example: some elite schools teach oenology. Now what could possibly be the point of formally educating people on the finer details of wine making and tasting? It's simply how the aristocracy recognise themselves. There are other class recognition examples: for instance, rich kids tend to play tennis more than they play soccer. I know third hand of someone who paid attention to his watch and smartphone to get a job (or a promotion, I don't recall). It was in finance. The idea is, if you belong to the right social class, you are allowed to go up. If they spot you for a commoner, you're not. Simple as that. Think this is a stretch? I'v read an article (American article) about how someone was denied a job because of how she dressed. Oh she was dressed all right, neat and all, but she also had a dark skin (okay, she was black), and here is what the boss said once the interview was over: "my, you don't wear a tank top under your shirt, you wear a silk shell!". Such a little detail, but that was nevertheless a sign that this applicant was perhaps not as rich as she should have been.
