So theres this girl I've been following on snapchat for a while i've seen her posts about other girls make up and I love her work. She just recently graduated make up school she posted something saying she will be doing people's make up for FREE for a whole week because she wants to get pictures of her work to put together a portfolio. I made an appointment with her because what a coincidence tomorrow is my baby shower. Okay long story short, if you were me how much would you tip her? I feel like her doing it for free is being too nice and I was thinking of tipping her $10 but then I thought that would be way too low so i'm thinking maybe $15 or $20. I've never gotten my make up done before so no rude comments please, I just want answers.
