This has happened to me quite often, and more than a few times after a first visit.
What does it mean? Are they hoping to increase the chances of rebooking? One told me that if i wanted to see her again i should only contact her on the public number, others have said i can book on personal or public. i am presuming it is for repeat business because only a couple have contacted me first to chat about non-escort activities. Are SPs just giving their personal numbers out regularly to punters? One SP made a huge song and dance about the face she was giving me her number as she was not supposed to do so, but in my mind i do not consider myself special, so i always think if i am getting it, so is everyone else.
On one occasion i was a little pissed off with an SP as her maid had kept me waiting outside and as an apology she said she would give me her personal number. This did not improve my mood.
i don't get it. if i wanted to see the SP again, i am fine to book the normal way. As my punting habits have developed, have got myself a punting mobile, so now have started turning down these offers as it is off most of the time, which seems to put their noses out of joint that i don't want their number, especially if i book a return visit.
