Jean a French Forrest Gump?
I don't think that he is really a credible character as some people claim. I never met anyone like him in my real life.
shareThen visit in a multi-cultural big city a few traditional (marginal) pubs, and you 'll see that these people do exist.
With all my respect, but I don't think that your real life is a good parameter then to judge if Jean is a credible character or not.
