My word! Something which appears to be your actual research on the pub! I haven’t had time to scour this but it seems distressingly right-headed for someone like me who likes to disagree with things in a curmudgeonly fashion. I have to say that some of the stuff about personal interaction (particularly the pub talk bit) may have been researched on the set of an Ealing comedy. Open arguments at the bar? “Alright there Lofty”? Once you get past “reciprocal gift-giving is the most effective means of preventing aggression between nations, tribes or individuals” (oh yes?) the section on round-buying is really rather good, I think.
I offer it to you, my friends, for consideration.
