Same here. Munches are at restaurants, the conversation is mostly non-risque, and newcomers, though made to feel welcome, are mostly left alone, free to join in to whatever extent makes them comfortable.
The only ones who wear leather arrive on motorcycles, and as is typical within the population, the subs tend to outnumber the doms, so there aren't all that many "head-masters' running around.
The group organizer also screens newcomers and keeps the obvious predators at bay. You can't just lurk and find out where the munch is held.
It's a great way to meet like-minded people.
