Goodness Icey Horror Stories to me.
My Experiences with Munches, Demo's, and Play Parties, has been Very Different, and Positive.
Here in the USA, and Nearly Every Munch I've been to (and that's been quite a few in different States and Cities), the Munch is held in a Public Place (like a Restaurant), and (obvious) LifeStyle Wear is discouraged. The ones where LifeStyle Wear is allowed are at Clubs or Private Homes. Many of which require one *Dress* After Arrival within the walls. PPL I have met at Munches have looked the same as Anyone you'd meet on the street. And a Munch is oftentimes a meal, conversation/discussions, sometimes games, and getting to know eachother and interests. Many discussions on Techniques, Building Dungeon Furniture, and other topic's of interest to BDSM interested PPL.
Demo's I've attended have been in Private Homes, or at Clubs where things were set up for them. Demo's are Great Learning Events for things of interest to Someone. Generally as Safe as WITTWD will ever be, or possibly can be. And Taught by Experts.
Master and I saw a Great FirePlay Demo for exampleAnd others.
Play Parties are typically in Private Homes, Only inviting, or being invited by, PPL that Know and Trust eachother. And generally there is a dress theme, like Matrix, or something <G>. Like a Costume Ball.
All these things can be such Great Fun, and Learning experiences, and development of Community, Friends, Mentors, Meeting Partner(s).
I guess like anything else, one has to be carefull where they go? And take things slowly.
