I had the same experience, but not with a machine - it was just by striking a conversation with a shop owner on Long Island's north shore - not even a ritzy area! The woman was a total snob when she realized that I was asking 'beginner' questions. I have always sewn and crafted, but had only started quilting just before my visit to that shop. She made me feel like an intruding lower class citizen and have never returned there. A shame really, for her, because I spend A LOT OF $$$ on fabrics now!!
