I agree that Sam shows plenty of her face in her showcase to make a decision. Wish I were in Dallas!
One other reason is the following. I saw an ad for a lady (no face) that I was immediately attracted to. She was blond, had good reviews and a killer body.
I set the appointment and go to her hotel the next day. I walk in the door of her hotel room ready to go and I am just stunned at what I see and it stopped me dead in my tracks. Nothing bad. Her body was super hot and she was a very attractive woman....that looked EXACTLY like my younger sister. I mean she could have been her twin....except for the body.
Needless to say that posed a very big problem and after talking it over with the provider and after I explained to her the problem we reached an agreement, hugged and I left.
Just one more thing to think about.
