If TV shows define a nation and it's people, that's really sad. "High Tea" is, indeed, a necessary and daily rite for some English. Probably totally dismissed by most. Even in the US in some of our hotels. Much like some pipe smokers make a rite/ritual out of loading and smoking. Or, maybe, own a car of some sort which they religiously wash and wax every Sunday even though the ignition hasn't been engaged in years.
After reading the numerous "tea" threads here, heavily doctored teas, heavily adulterated pipe blends, and such appear to be "de rigueur" for many. Hell, there are Americans attending football games simply for the "tail gating" rite. The game secondary if a concern at all. The first day of duck hunting is a "rite" for some.
