So had arranged a 10pm meeting with Megan earlier this evening. Had agreed that I would message her once I had landed at Heathrow and got my way to pick up a hire car. I did this, headed towards her Incall location, and shortly received a message stating that she would not be finished on an Outcall till 11.30pm..!!
How nice. She obviously took the opportunity for a more expensive Outcall Appointment for an hour or two - and just neglected to tell me about it.
So she gets a Negative for messing me about, wasting my time and ruining my evening.

It's a shame to have to give her a Negative as her feedback seems very good. But that tonight was well out of order.
