Thanks for the warning, I was in Hawaii once and there was a woman who was doing henna tattoos and she also warned me saying if you ever see someone doing henna tattoos using black dye DO NOT get it. She was really serious about it, it was almost scary. I hope things turn out okay with your grandson, all the little kids in my summer camp come back from vacations with a million little tattoos too lol they love those things.
I hope he is going to be okay and there wont be any permanent damage. Glad to hear they are going to do something about getting this place shut down. Keep us posted sara
