I know it was a long time ago but in 1995 I had to pay for the next week by Friday of the previus week or my son couldn't go. I had to let her know what days (this was after school) he would be there. If I needed to change a day that was an additional charge, She wanted all kids picked up by 5:30 - if not it was $5.00 for every 15 minutes I was late. I was in realestate and my schedule was all over the place. It was so hard that I had to find someone else. I do understand that you don't want to get walked on. Good luck.
