I know which one you are talking about. I know I am a weirdo because I prefer to be left alone in a quilt shop, so my perception of unfriendly probably doesn't match yours. The staff at that shop does leave me alone but I don't remember anyone being unfriendly. They have lots of fabric - that's all I care about.
And I have also visited the Sedona shop several times and never had a bad experience. It is a great shop.
Sorry you didn't have a wonderful time after all your driving time. You might want to let the owner know that you made such an effort and were disappointed. I'm sure you were really looking forward to the visit.
