Need some mother in law advise please!?

My husband and I and our families went out to eat at a Hibachi Grill this weekend for his birthday. His Mom complained the WHOLE TIME! I can handle complainers, but her, I can't deal with any longer. From how her drink tasted, to how the food smelled when it was cooking, how she "helps" my husband out, and to how she was SO broke she really couldn't "pay" for her meal...it was ridiculous. She is SO materialistic. She is always calling and complaining to me about how she is "always" broke, but constantly goes out to eat and shops all the time!? I get tired of hearing it every week. I finally started telling her that her definition of "broke" was different from mine. If I am broke, we can't get groceries or pay our bills. She says her definition of broke is not having some "spending" money! Anyways, to make a long story short, I am tired of her antics. She never tells her kids she loves them, and every time my husband and I are at her house, she is ALWAYS on his case. Saying things like "don't make a mess" , "don't touch this, don't touch that" , "i'm so broke i can't breathe" , "when are you going to do this/that for me" , "blah, freakin', blah!!!!!" I am Ticked Off at her right now for being such a witch (only with a B) on his birthday. She can't ever just be normal and happy for her kids. She makes EVERYTHING difficult! She even said at his bday party "I am getting such-n-such to eat. It's $30 that I really don't have to spend right now!" OMG! My question is this. How do I deal with this? My husband agrees she treats him so disrespectful. Hes my husband, and it hurts my feelings that she treats him like this. He had dealt with it his whole life. He said he just puts a wall up and ignores it. That's not fair nor the healthy thing to do. She normally calls me about 3 times a week just to "talk" aka complain. I think she knows i am ticked off at her. So when she does call, I was thinking of confronting her about how she acted at the birthday party. Do you think I should or what would you do or say?!?!!? Thanks so much in advance for the advise & sorry its so long! :)
