I recently had to leave a bad review for a local quilt shop after my third bad experience. First time I took one of their classes we were instructed to use the same color in each block. I decided to change mine up and used a variety of colors in each block. You wouldn't believe the furor that caused. The teacher addressed me as "The Rebel" all day. It was a couple of years before I signed up for another class at that shop - I showed up 15 minutes before class time, as had several others and we were all sitting in our cars waiting for the shop to open. At the time that the class was supposed to start, the teacher finally drove up. And guess what? She didn't have a key to open the shop! We all stood there waiting for the owner to show - except for me. I waited 5 minutes and went home (because I'm a rebel).
