And why is it your business? What if it was a piercing? Or a tattoo?
Do you want her to deny service to you because she doesn't like your haircut... or your shoes... or your shirt? Does she have the right to do that? I don't think so... and you don't have the right to impose your beliefs on her, since she was not breaking the law.
I agree with WebstersII: "Get a life."
WOW! I am really understanding why our Country is in the sh*thole. We have people like you putting us there. I am her customer, I am paying her salary, you and webster might want to look that word “customer” up. I would definitely feel the same way about a tattoo and a piercing. It doesn’t belong in the work place. I do have a life, a life of “morals”, another word you might like to educate yourself about.
