That was something I did notice with my time in the French Rivera. A lot more friendly and accommodating to us when we pulled into port down near Nice.
Everybody from outside Paris hates Parisians (I'm obviously generalizing but it does hold a lot of truth) and we do deserve it, entertain it, and work for it and there is also a certain jealousy (massive GDP per capita and average income disparity between Paris and the rest of the country and the country and economy are very centralized towards Paris making the rest second class).
People from the South will usually be the friendliest to foreigner (and the most defiant to Parisians) but generally every French from the countryside will be much more friendly and open than Parisians.
God knows how much I suffered of my inherent clickiness especially when living in Spain but also in SA, the least possible clicky place. I was literally outcasting myself. :crylaugh:
