I only go into JoAnne's when I really need something. I've run into long lines as well and it's so frustrating. However, one of the sales girls used to go to high school with my son so if she sees me in line, and if she's working that day, she will take me to another register. I know it's prejudiced but..........
I usually go to a local fabric store even though her fabric may be a little higher in cost, I really prefer going there because she only carries the best fabrics and I feel it's worth it.
