Late Pick up

[Crayola kiddies]

If she is late again today I would say to her " just a reminder I do close at xxxx" if this becomes a habit I would increase you late fees to something like $2/minute for the first 10 minutes and then $5/minute after that to deter her because obviously a flat rate if $5 is not enough. The late fee is supposed deter people from being late not encourage.
