Got out of my appointment and i wanted a slip so I can show at work. I ask at the front desk (women center) and the lady their was just plan rude! Saying to get a number bcuz their is more people that have an appointment (nobody was checking in). I explain to her I have a number just got out of my appointment and told me to ask for a slip on the front desk! Even after I explain to her she still acted stupid and told me to seat!
