No debit under $10, which I've never heard of. Credit, maybe, but debit? So my eyebrow threading was $7 and having not been there before I didn't bring cash. She asked if she could add $3 to my bill to do debit and I said absolutely, I would have tipped that much anyway! She started arguing that no, I have to tip on TOP of the extra money she's charging me. I'm sorry? I'm not paying you $3 to pocket and then extra tip on top of that. The principle of it annoys me but if the threading had been amazing I may have been willing to go back and make sure I had cash, but I've never had threading hurt as bad as when she did it. Only redeeming quality was that it was one of the only places open and there was no wait at all. Bad sign perhaps?
