I'm sorry this happened to you twice.
I'm with Adrienne Baptiste- I want to keep my reputation as clean as possible and so I can't afford to "flake" on clients
I say it over and over again but I believe in mutual respect for time. We all have lives and yes things happen but there are very few reasons to NCNS when you set something up with ANYONE for anything... whether it's to see an escort or to have dinner with friends. If you don't want to see someone anymore? At least tell them instead of going radio silent.
Here's my pitch

-
My photos are well done, true to profile, and I am 100% the person you'll see when you open the door and the person you read about in reviews. I have multiple options for screening, including one that is newbie friendly. For the purpose of safety and secure handling of personally identifiable information (PII), I believe in personally managing the process of screening and scheduling. As long as you are honest during screening and I am able to verify that you are who you say you are (and thus safe to meet), I am happy to meet when our schedules line up.
In these incredibly polarized times, I kindly note that I never discriminate based on age, race, ethnicity, religion, gender, sexual orientation, or political beliefs.
That's not to say I'm a perfect person. I manage everything from start to finish. But I give it my best.
If there's anything that leads me to believe we would of be a good fit for one another, I would never mislead someone to believing we would meet at a date, time, and location and then disappear inexplicably. That is DANGEROUS and a needless invasion of a client's privacy plus a waste of his/her/their and my time.
And my black lady friends in the DC area like Mia Paige and Lauren Barnett are the same. (Shameless plug).
So if you are in or visiting the DMV area - DC, Maryland, and Virginia - and reading this, please don't be turned off by this person's account of our providers. I don't say this to invalidate his experience, but just to say - there are many wonderful black providers in the area who are beautiful, skilled, and professional.
