I don't know about snobbery, but whenever I go to a folk club, which is rare, I always feel that I am gate-crashing a private party. Everyone seems to know one another and while there is usually a good atmosphere, if you are not a part of the group, then you feel left out. It makes you feel conspicious. Not only that, in order to get in, you have to become a member. Why? It is a shame that folk clubs can't be just venues where you pay your money, go in, and listen to whoever is being advertised outside. That's another thing, folk clubs are damnable hard to find and they never advertise.
