I was looking through some rail, one near the till and I was looking at some trousers for a while, just seeing what they were like. I could feel that she was watching me. All of a sudden the assistant said 'they're a size 20, I don't think they'd be any good for you.' Aibu to think this is odd to comment on? She doesn't know my size and I felt like she was a bit strange to decide what would be good or not for me.
