Make the fees steep to begin with, as you never know when this might extend to multiple nights a week. It’s a slippery slope once you say yes the first time. My late fees are $20 per half hour, and really no amount of money will make up for that child being in your care for an hour after closing. For me, it’s too much of an inconvenience to have an extra child here to infringe on my own family’s time for dinner/extra curricular activities/homework/baths etc.

Work that long of a day.
