The one who carries the pizza to your door walks the pilgrim’s road so that you may feast. To receive their labour and give them nothing is to take the slice and discard the person — a cousin of the second grave sin.
Reward those who serve you. Tip well, thank sincerely, and remember that fellowship does not end at your doorstep.
