In the past if I have cancelled, usually the day before at the latest, I always re book and make it up to the girl. Whether it be some, wine , champagne, or even Scotch. I always hate doing it, and well shit happens.
I had a recent experience with a SP in Toronto whom I have been wanting to see for ages. It just so happened I was in Toronto for business so I made the appointment. Texted earlier in the day and all was still good, got to the rendezvous point and no answer, no text, no email, no phone. She emailed me later saying she had slept past her alarm, it was a late evening appointment. I gave her the benefit of the doubt and she promised to make it up to me, which I was fine with.
I set up an appointment 4 days later for a visit in 48 hours. Everything still a go, that is until the day of the appointment. She is not answering her email, texts, or phone. I am annoyed and pissed beyond belief at this point in time, but I know shit happens. I send her an email, not too lengthy, and explain how upset I was and I also told her to reach out to me as I still would like to see her. It has been over a week with no response.
She wasn't a newbie or fly by night, she is well reviewed and been in the business for at least the last 3-4 years.
