Closing early one day for health procedure (but not taking a day off)

[kindredspirit]

I have one child that is picked up 15 min after I officially close. This is in their contract, and doesn’t cost extra (they drop off later and other perks). They have also been much later on occasion. So if I have an appointment, lesson, etc, I tell them they need to be on time, or that I am closing early, and they either take off work or get a grandparent to pick up.

In your case, I would tell the parent you have an appointment to get to, and if they can’t pick up early that day, you will need to close for the whole day.
