I came across that stuff surfing the web: http://pasta.e-rcps.com/gripes/
This is a booklet first published in 1944 for issue to American troops. It tries to explain the cultural differences between France and USA to GIs... The book consists of a list of complaints, each accompanied by a patient explanation of why the French are as they are and whether or not the complaint is valid.
This booklet was recently republished in France under the name "Nos amis les français" ("Our Friends the French") and it was last summer best-seller in France. I put it on top of my christmas wish list, a must-have for a french immigrant like me!

I have to agree with some of them:

• 42. "Their toilets are appalling." Let's face it, French toilets are not appalling like they were probably in 1945 but in general are still less clean than American ones.
• 29. "The French are always criticizing... That is sooooooooooo true, I would also have added complaining. But if you know the french culture, you know that most of the time it is just for the pleasure of it, we don't really mean it ;-)

Some of them were probably true but are not anymore:

• 45. "The French don't bathe.", the author rectifies the complaint: "They don't bathe often enough." :-) I can tell you I definitively wash more than the average Riverside inhabitant ;-) (Riverside, California, where I live)

Interestingly enough, you can even find some complaints that are now reversed, French would say that about American nowadays:

• 30. "All the French want is a good time. That's all they think about in Paris." (Replace Paris by L.A., Vegas, New Orleans, Miami, etc...)
• 67. "French railroads are a mess." (you could also add electrical grid I guess on this one...)

My personal favorite:

• 48. "I'd like the French a lot better if they were cleaner." Followed by the comment "That's perfectly understandable." :-)

Anyways there are 112 of them. It is kind of sad that 60 years later, it is still almost the same misunderstandings...
