I have only had one bad experience with a store. I was given an old Viking computerized sewing machine. So I took it to the nearest dealer to ask for help on how to use it. They never had time for me. They had time to try to sew me a new one but no help on the old one. There's another LQS nearby that her business has increased so much she had to move to a new building with lots more space. She and her staff are so helpful and I have bought several machines from her. The only difference is that she will charge for classes on how to use a machine if you did not buy from her. If you buy from her the classes (just the "how to" on machine usages) are free. When I bought my serger there, half the people in the class had machines they bought somewhere else and we were treated all the same. Now that's customer service!
