I love my Jo-Anns. I have had several positive experiences.
Last week a young 20-ish mother was buying some orange netting to make a Halloween costume for her baby who looked about 9 months old. She handed the bolt to the cutter and the cutter asked "How much?" The mother said "I don't know. I don't sew." She explained what she wanted and the two cutting women not only figured out how much she needed but also told her how to construct the tu-tu.
Another time, I had fleece cut which made a big mess on the cutting table and my other fabric. The cutter produced a sticky lint brush and proceeded to de-lint all of my fabric.
There is nice customer service at my Jo-Anns!
