I have been to Joann's exactly once. I do not sew, but needed fabric for a project. No customers at the fabric counter, so I'm thinking 'cool!'  Yeah......the giant fat wench behind the counter refused to acknowledge my presence, despite the fact that I'm standing right there, at the counter. After a few minutes of her piddling around, obviously avoiding me, I said, "Excuse me." in a cheerful, non threatening way. (I was raised to be polite, what can you do?). Fatty spins around, glaring at me. Not even a greeting, just this hostile look. I managed to get the bit of fabric I needed, without a single word or courtesy from her. WTF? This was years before FPH or FA, so the obvious hatred kind of blew my mind. Not any more. In fact, I expect it. Although I remain courteous, I always expect rude service from fat women.
