1. Any correspondence must be professional and devoid of drama.
2. It goes both ways. A provider is offering something. A client is paying for something. Only when the two terms are amenable does a transaction result. There are stipulations on both sides. A client is agreeing to the terms set forth. That could be mean a list of expected services that the woman provides. And a provider is expecting the client to adhere to her stipulations (for example, being discreet, confirming at a particular point in time, arriving clean and fresh, etc.)
3. Last-minute cancellations are never taken well, and each side needs to see the other side. I had an UTR girl who I have been seeing for a few months now on an almost-weekly basis start to get a bit too demanding with my time. For example, we have been unable to meet the last few weekends because of various issues in my schedule. And she usually comes over for about three hours and charges me some ridiculously low rate without watching the clock. This last week seemed ideal to meet, as my work schedule was curtailed. I proposed Tuesday night or Wednesday night. She said she was busy, so I said, "Okay, another day." Wednesday afternoon she asks me if I'm free, and of course I have made other plans. She seemed to be disappointed, but she didn't understand that this is last-minute for me, and I don't spend all my time with her, but I had to be clear about needing a heads-up before planning anything. Anyway, it's a long way of saying...be delicate and understanding to the other side.
4. Having been the recipient of a last-minute cancellation one time by another girl who said, "I don't think we are a good fit," after having been screened, booked, and confirmed, I wasn't really happy, either. However, these things happen. No need to trash her on the boards or write a bad review--well, because the session never happened! But I imagine that with many other guys, if they were really looking forward to a session and had been planning around it...well, that could be a big disappointment, especially if they had to do some major juggling to see you.
5. Good communication is always appreciated. I scheduled a session with a provider tonight over two weeks ago. She went on vacation the last week, and we corresponded once. It is almost 10:45 am on the day of the appointment, and I still haven't received responses to my last two emails about a time and place. This one may very well end badly. It sucks, but I will deal with it professionally if that's the outcome.
