I charge the same every two weeks, no matter what, their fee never varies. They pay a tuition not by attendance. Look at it this way if you pay a tuition for college/university and you don't show up to class do you get money back? NO they don't care if you don't show up thats your problem if you miss out. Why should we loss out on our income because their child is sick, on vacation or grandma comes to visit for a month and the child doesn't need care. We are running a business not a charity so that our clients can save well be can't pay our bills.
