Her pricing is budget, so I would expect her to make up the difference with fees for extras. I also suspect that WGs make a judgement in person based on the punters looks/hygiene on what's available and what they will charge for it, so that might be partly why it's hard to get pricing before hand. But mostly this one seems high risk of getting cold and distant vanilla service, rushing, etc, nevermind the extras like OWO and CIM.
Of course Mr HP would be a good person to check her out, using his stringent 4S system.
Her young age, looks, and affordable rate are tempting for me too. I'd TOFTT, except she's about 2 hours away and seems a high likelihood of not passing the 4S.
