It is actually quite ridiculous what the courts let people get away with concerning suing. If people didn't actually win frivolous lawsuits, they wouldn't be so popular... then again, there are a lot of stupid people in the U.S. (and every other country too), but I think our population density helps further the amount of dumb/silly/inane lawsuits; you know, more people = greater number of perceived loonies.
As to the sex worker... there are a lot of positions she could have utilized, so it's her own fault if she never changed it up any. Ok, okay, in er case she could have used some *other* accessories besides her hands; at least she was getting paid to, well, you know...
