I agree, if nothing else the shop owner will wake up and not allow his sprog to be there.
He should have offered to do whatever was needed to restore her art, she shouldn't have to press him or hire counsel. If it were me I'd leave a review stating exactly what happened because the public deserves to know that this tattoo artist doesn't have the sense to keep his brat out of the business. This could have easily been avoided.
I don't know what those idiot parunts were thinking by having their sprog there. Once she started acting her age and showing clear signs of boredom the moo should have left with her immediately, oh but she was occupied on her stupid phone.
And for the moo to hit her for acting her age? She is way too young to understand that she can't play with her duh. If anyone deserves the proverbial slap in this instance it is the moo and duh.
What if the brat ended up tattooed? Or worse, what if the tattoo gun ended up being launched into someone's eye or similar and caused an ER visit?
