So sorry about your bad experience. This is not the norm, at least not in NC! I find shop owners, and especially customers, full of ideas, ready to share, teach, lend ideas and techniques, and wonderfully willing to help. Next time you need help, come here and post questions. I am a novice too and have learned so much from reading posts from the experts who frequent this site!
Don't give up! Your next quilt will be a masterpiece! Hang in there! Every time you complete a project, you will get a little bit better!
