Do the French eat lots of French fries?

The term "French fries" probably gained purchase from President Jefferson, who described them using the phrase "Pommes de terre frites à cru, en petites tranches" ("Potatoes deep-fried while raw, in small strips") but also referred to them as "potatoes served in the French manner."  French-fried was for a time considered synonymous (in the US) with deep-fat frying.  What we see in France is that the French do not frequently eat fried potatoes, although they do like a little "McDo" every now and then--although they will be the first to criticize this "cuisine Americaine."  

French McDo's are much fancier than the average McDonald's in the U.S.  They are known for being extremely clean, with a futuristic architecture and often with high-tech automated ordering systems.  In Paris, my experience was that I ordered and paid through a slick computer interface and then picked up the meal from a human being, but this might not be the case at all locations.  It is always possible to complete the transaction completely with a human employee.
