Definitely real.
The exact same situation happened to me. Except I saw her leave the venue at my booked time with her blonde friend and they got into a cab and left. I tried making another booking, booked again and no confirmation of details or anything. I'm not really sure why she won't see me (I have excellent feedback) - unless she's just made enough money by a certain point and then just decides she's done for the day and doesn't even give the courtesy of a cancellation text.
Anyway, I want to try again but I've managed my expectation that it is very unlikely to ever happen.
