This is why I try not to say when I close I ask what time will you be dropping off/picking up and then if it doesn't work for me I let them know. My hours are 7-5, one girl though on the dad's days doesn't get picked up till 5:30 same thing started getting out of control, I told them they needed to start being on time. I had another girl to that started happening with I almost quit in the spring because of the stress you need to tell them they have to be at your place for such and such a time change your hours even just say now I will be closing at 5pm. Good Luck it is hard but the stress was awful they were driving me nuts soo disrepectful!!
