Was 5 minutes late with a three month old, have over an hour drive to get here. Waited and hour and 20 minutes haven't went back or anything when I had told the lady at the front desk she said well you were late so it will be 30 to an hour more to wait... the appointment was for a three month old... the waiting room was empty at times. I had another appointment to go to two hours after that one while I was in WS, NC. I make my baby's appointment on the same days different times.
