Thank you ladies, I learned my lesson why because It happen two times she came at 5:30 and didn't say it the first time, so she of course wanted to come at 5:30 so now that she showed up 10 minutes late, she argued the late fee, I can't believe it. anyway thank you for the support I'm writing a letter to her saying if this happens again and she comes after 5:15 is a late fee and if she is not willing to pay she is out on the spot.
