Late drop offs dont bother me.

I have no problem saying at drop off "Oh xx just missed snack/craft etc. To hopefully have the dcp get the point.

I do not tolerate late pick ups. I have 4 other children and enough to do each night. I have all the dck dressed and ready at the door. I say "sorry can't chat we have xxx tonight have a good night see you tomorrow" All my dcp know we have a very busy evening schedule.
