Another thing that has to be taken into account is what kind of club it is. If it's an established game group or card group, it can be very difficult to let a new person in. They may need to be at a certain level, you would have to take time away from playing to teach the game, the rules of the game, etc. Some people aren't good at teaching, some aren't good at understanding how to play.
There are some who may be good at certain games and some who aren't. Not everyone is compatible to play certain games together.
I played Mahjong for several years with my friends, but I am not that good of a player. I can't imagine walking into a group of Mahjong players who are established and maybe advanced and expect them to want me to play. Maybe they don't want to make new friends, they just want to play their game and socialize with those they know.
Now should I walk into one of the card rooms with a group of my own, I'm sure we would be more than welcome.
