Take the family/friend discount?

So idk how controve this us but I wanted to see what everyone here thinks because most are big on tipping, etc.

Here's the scenario: My friend recently became a licensed esthetician and offered to do my brows for me because I was over due. I was totally down and she came over to my house to do it over a glass of wine and girl time. When it came to pay I asked what I owed her and she wanted to give it to me for cheap for a family discount. Now idk about starting in a self employed sort of business like this but I insisted on paying the regular price and gave her a big tip. My reasoning is she is just starting out and probably needs the money to grow more and shouldn't be expected to give friend and family discounts at this stage. My husband didn't understand why I didn't take the discount but it just felt wrong. What would you guys do or have done?
