It's a shame really, as its the ones that are not that high on my list to revisit who have texted.
I have in the past asked girls to let me know when they are back working in the area and I've rebooked, and that's worked well, for both parties, but I don't count those as unsolicited messages.
A message out of the blue from a previous booking saying 'im in the area, do u want to book?' is, in my opinion out of order.
Particularly when I visited the girl who texted me today, previously, she offered a duo, of which I accepted and had a good time, but she asked me not to mention the other girl in my review, so discretion only works one way?
