Would you repair a single chip in Shellac a week after application for free? Or would you charge. If so what is reasonable? I've been doing the odd repair for nothing but I'm getting a bit irritated as I know these two particular people don't look after their nails properly - in fact they laugh at me when I give aftercare!!! They say they've heard it all before and then proceed to tell me what cleaning and chemicals they've had their hands in with no gloves on! I'm feeling a bit of a mug at the moment!
