I AW e-mailed her to tell her that her rates didn't make sense, as from a punters point of view, it would be cheaper to book her for 30 minutes, go out, and book her again for another 30 minutes.
She laughed and said that maths wasn't her strong point. I can see she's adjusted them but as you can see it works out cheaper to book her for 1 hour, rather than 2 or 3 hours. Dozy bitch!
