Wow, you really struck a nerve! I also think genuine friendliness and helpfulness are the most important thing. I've been in so many quilt shops and yarn shops where the help isn't friendly or helpful. A helpful, friendly shop is a real joy. About classes I just think they really need to be about quilting. One new shop near me has lots of classes but they are all geared toward selling expensive sewing machines. Good luck with your shop if you do go that route.
