My husband always says that everyone is a potential customer. I worked as an account receivable clerk and dispatched orders for a propane and petroleum company for 8 years. I always put a smile on my face even when I didn't feel like it. I left that job in 2004. Just yesterday, I visited with one of my customers at Walmart. He is in his 80's now and still remembered me. He couldn't remember my name, but he knew where I worked and that I was the girl that always smiled.
Life is too short to let other people ruin my fun. Keep on using your machine and enjoy every stitch. btw - I sew on a Brother cs6000i and I do enjoy every stitch.
