A little off topic as your question is more at the definitional aspects of "flake" but as I have stated before:Much has been written about the frustration for hobbyist when a provider flakes on them. The consequences for providers when a hobbyist flakes on them is harder on them, but that is a different topic. Get VIP Membership and do the research and a lot of the provider flake issue can be avoided.
However, some of the best providers in bed are the shit when it comes to operating on good business principles. Also, a number of people including providers, live in the moment, which can make their lives unmanageable and causes a lot of drama to surround them. If you play with these types of people you have to adopt an “I’ll believe it when it happens” attitude with no expectation that things will come off as planned or suffer a lot of frustration and aggravation. If you have the time and flexibility to work through the chaos some great sessions can be had. Again this is not for everyone and not a standard practice for me, but at times it can have a certain thrill and excitement appeal. When a hot time with lady is not a sure thing there is a certain joy that comes about when you do score.
It should be noted that there are a lot of really hot passionate providers that manage their business well and are dependable. Reading reviews and using VIP search options they are easy to find. One can have ideal sessions without ever being involved with the flaky ones. Also, not all of the flaky ones are good in session. Just another approach to the hobby if one chooses to be adventurous and has time and flexibility. When reading the reviews one can generally tell the hot in bed flakes from the just flakes with no redeeming service qualities.
