Do they think green means gullible?

Simpler than that - they (and their customers) consider themselves to be green. It's not cynical - they don't see any contradiction between believing in some bits of science (e.g. global warming) and also believing in reiki and vortex healing and so on. (I don't know what vortex healing is either. I may have made it up.)

We had some fine singing and tunes, anyway - that's the main thing. Thanks to Les, Ged, Kate, Helen, Dave, Gordon and everyone I've forgotten (that cider was very strong).
