Need a part time job!

I am currently looking for a part time job just to bring in a little extra dough. I had a job interview at Macy's today and it went so well until, she told me they aren't even hiring! I don't understand why companies conduct interviews if they aren't hiring. I worked for Meier and Frank which turned into Macy's all the management remember me and I would have the job but wait they have no openings!! I am just really frustrated because it would have been perfect. I hope something else pans out. I want to not have to worry about any finances. I want to be able to do a few little extras and not worry about what bills need to be paid!! That is my frustration I just want to provide the best I can for my family and I feel as if I can contribute more. It just gets frustrating!! I just want everything to work out!!
