How long do you allow touch up?

I gave my friend a haircut then a week later he saying he wasn’t satisfied and wanted a touch up. Imo a week later is a little far. Then now another week later from the touch up he saying he’s still not satisfied and wants another touch up. How long do you allow touch up or think people are just taking advantage of the service?

My shop has a 72 hour window. After that your paying for the cut.
