What of the ADD student who gets distracted when someone comes in late? What should we tell them. "Suck it up"

What of the daycare that's expecting you to show up and pick up your kids on time. Should we tell the workers to wait, because the guy replacing you at work was late. Then of course we tell the cleaners of the daycare to start their shift 30 mins later because they have to wait for the last kid to leave. Oh and the cleaners will have to stay 30 min extra to clean, so now we tell the people relying on them to wait. Or.. Or we tell the cleaners to work a bit harder so they don't take an extra 30 minutes..

So the 30min you're late messes up the day of not just the person expecting you, but all the people expecting them.

How about on principle anticipate that you're going to be late, and make an effort to arrive early. If you know you're late all the time, start giving yourself more time.
