Well, she is a bitch and abused the situation to make profit, even if it limited to a certain amount of water she can materialze daily. But then again she didn't make a big secret of it. So I'm not really sure you can call this scam, as a) the amount of her goods might be limited and b) she doesn't even try to lie to the people, that she uses her position.
Maybe my taste in women is a little bit bad in this case, but I can't really dislike her for now. I mean she has a nice pair that suite her and her out going facial expression are kinda charming. Being the saleswoman, being flirty, being the villainess, being smug, being destroyed. She's funny. 🤭
