"treated" meaning you will give her a free service/add-on? I hope you won't do that. You want to make money, right? I offer Gelish Structure Gel (which is a thicker soak off gel kind of like Brisa Lite) for a small fee. I let people know why I want to use it on them, how they would benefit, and people usually say yes. Then when they come in again I make sure to ask them how they liked their nails with that structure gel service. Then they are hooked to have it again. I have even had clients ask for it once their nails were in good shape because they liked how much stronger it made their nails seem having a thicker coat of protection on them. So, freebies can be great as long as maybe you let them know that "in the future" there will be a charge for it. Just wanted to discuss that bit that caught my attention in what you wrote. Thanks!
