I think the family hired her through the proxy service or the man wearing the glasses, so there's a possibility they didn't really meet her face-to-face till now.The only thing that doesn't make sense was the family that hired her acting like she was plagued until she gave them money (the mithril ore) and then she wasn't so bad. It was realistic, but they were waiting for her to bring back their daughter but then don't want to interact with her? That's like if I went into an auto shop today and refused to interact with the mechanic and only talked to the sales clerk and went full Karen if a mechanic even tried to ask me a question about my car.
