Recently I had visitors from Europe, who are friends of my children.  One night I took them out to dinner at a restaurant, and the elementary-school-aged visitor announced to the table, “In American restaurants, if there isn’t anything left over at the end of the meal, you haven’t been served enough food.”  I am not sure when he had last eaten in an American restaurant, but I didn’t ask. And yes, I have heard Dutch people make boisterous announcements about France on ski lifts in the French Alps, and Americans opining loudly about Italy in the Uffizi.  I’ll never, ever get away from this behavior, I thought.
