Sounds like everyone covered all the basis. Friendly is #1 for me. Treat me right and I will be back even if I only have the money to buy a fat quarter but I will talk your shop up to everyone I meet.
About 4 years ago my brother took me to Kansas to see my grandaughter we also went to Denver to see a sister I hadn't seen in a very long time. On the way we passed Golden. We went to the museum there and when we came out there was a fabric store I believe across the street. The lady was closing up but let us go in anyway. She was very sweet and friendly even though I don't think I bought anything. I did try and hurry but she didn't not rush us out. That is the kind of shop I like to go to. :-)
