Tale of two providers, one pro, and one not so much

So I was in Memphis visiting, contacted a very well known respected provider. Donation was set and agreed upon for hour outcall. After seeing her it was discovered thT she had to take an uber to get to me. She never mentioned it at all. Also never asked for a deposit. Couple nights later I contacted a not a pro and she said she would need an uber. Said it would cost an additional $50 on top of hour. I was OK with that. Then she told me it was $15 for every 15 minutes she had to wait to be picked up. A dollar a minute wait time. I passed as it was getting too complicated. I guess the point is there is a clear separation between proven professionals and sketchy fly by nights. That is all.
