I hate the back stabbing *&^%!! Don't let them get to you emotionally. They really can't do much to you anyway. Not physically, financially and not mentally if you don't let them. I would talk with the owner so she knows what is going on and that you are going to pull this one woman on the side and have a word with her.

Bullies usually back down if you confront them. they typically deny any of your claim. So just tell them that it doesn't matter what she thinks or claims, tell her that you don't appreciate the b*&y attitude and adolescent behavior.

Now, if the owner of the place thinks its more important to keep the clique, then cancel your membership because it just means that the clique is more important than you. I wouldn't bother giving money to a place that doesn't have any interest in my well being.

Easier said than done but don't think about the stupid comments or epithet thrown at you. Try to brush it off as a sign of their immaturity.
