She started as my stylist, but now we are friends. She suggested I come to her house for my haircut so she wont have to split the cost with the salon. So I am assuming that she will charge me less than I would pay at the salon but where she can still make more than she would after the salon takes their cut. We are going to have dinner together that night too. Anyway, since it is on more friendly and less professional terms I wasn't sure if I should still tip.
