Heh, the community I was in often had munches at a private house so that scenes and demonstrations could happen ad hoc when participants couldn’t resist. Munches are typically held at neutral locations like cafés or restaurants so that no one feels at a disadvantage, and more intimate encounters would have to be scheduled for later (or occur after the meet at someone’s home).

So the possibility that people might get laid on site added a particular je ne sais quoi, and a particular risk, to the occasion.
