for a hooker's life to be a mess. Not unlike strippers. Many have it all together, many don't. You won't see that when they are with you and deal with you, because that is their job. So it often shows in no call backs, reschedules, delays, and excuses.
Another factor is that many don't actually work well with an advanced schedule, and don't even actually make one, even when they talk to you like they do it. Ever noticed you always need to call the day of, and then are asked to call back again as time gets closer. This is more common than not.
Before the ire of the women that have their act together goes through the roof on my reply, this is not the case with 100% of them. There are some excellent and well organized busineess women out there.
If you are the type of whoremonger that gets to know lots of them them personally, you start to find out about the high level of flakiness. One veteran whom I've had many interesting conversations with over time, and who knows and has known many professional women told me that she has seen substance abuse of some type in more than half of all the pros she has met. That certainly will make being on the ball tough.
Keep in mind that only a fraction of pros are ever going to post on this site, so the quality women posting here are not a representative sample.
