The phone call versus leaving a note analogy is the clearest way I have seen this explained. The checkout example with order 4821 makes the failure mode concrete, because one slow step should not hold the customer on the line. I also liked the honest trade off in the table, that the sender gives up knowing exactly when the job finishes. Starting with a dead letter tray from day one is practical advice I will remember.
