She had strong views about that and wasn't shy about promoting them.
- STIs. As a professional, she had regular check ups.
- Reliability. The professional shows up when he wants it, not when she maybe feels like it. (I learned later this was BS - she would sometimes stand up clients and go shopping, claiming she forgot)
- Peace of mind. She goes home afterwards, and doesn't stalk.
- Lastly, she was confident she was amazing in every way, had glowing references on review sites, and that girls like her were simply not to be found on Tinder. I never had a Tinder account, so I can't be sure, but I do think she overestimated herself! :-p
