I know a few of these guys. They're all amiable sorts - go figure!
Go figure? Nah, it makes perfect sense. Drinking craft beer makes folks amiable. Just look at an NHC as an example. Thousands of happily drunk folk together for days with no aggro, no drama.
How's this for an (implausible) scenario...... get all the world leaders started on drinking craft beer. Then get them together for a big bottle share. Each one brings great beer from their country. They sit around the table, sharing beer, talking beer.... then when everyone's happy they can solve all the world's problems. The difficult part is to get them all drinking craft beer!!! But, hey, it could work.
