My experiences at NYAW were really excellent. I've only been to NYAF once so far and had a very good time. NYAW had and NYAF now has a nice roster of girls, many really highly reviewed.
If your 10 experiences at NYAW were satisfactory and given the roll-over of management to NYAF, why let a single bad experience with one girl cause you to never visit again?
Sally (or Sophia or Margie, whoever is handling their account here) made clear they want to make it right and keep you as a customer. Consider giving them a chance. There aren't many places as well run.
