Isn't shitting on U.S. culture (e.g. "oh at least we don't do x!") while driving home with a Big Mac one of the most Euro things to do? I've seen various shades of this in the U.K., France, Italy etc. I'm not sure I would be getting out the small violins tbh as the friendly animosity is kind of funny. Western Europe is essentially NA-lite economically and politically anyway.
