Parents abusing pick up time

[jodaycare]

I used to be open till 6 but now that I start at 6 am, I refuse to work 12 hour days. The Mom that is picking up late every Thursday, drops off at 7 am and only works 15 minutes away. Some days she is here by 4:45 so she must finish at 4:30. The other parent that is here at 5 on the nose or a few minutes past is a real estate agent and there have been times when he has arrived at 4:45 but sat in his car until 5 or after. I have cameras so I can see him so the next time he does it I am going to take his child out to him if I have no one else here. My late fees are $1 per minute and $5 extra per day if the child is here more than 10 hours a day.
