Do You Have the Same Last Name?

My hairdresser is my cousin's daughter. We are close in age and definitely knew each other when we were younger but haven't been to family events at the same time in many years. I have now been going for a year about four appointments and the fact of us being related has never come up. It's important no matter what you do that you do it after you have paid for the haircut so it does not seem even like a little bit like you are like let me get that kind of cousins discount. There should be a precedent set. Once your hair is cut if you don't want to pay they get another 30 minute go at your hair before you get to leave.
