In office leagues, the loser stocks snacks for the entire office, not just the league, for a set period. Coworkers outside the league benefit from a punishment they never knew occurred, which is somehow the funniest part. Requests get more exotic weekly.
The long haul: this is not a one-afternoon sentence. With a time commitment of one month, the punishment keeps paying out (for everyone else) long after the season ends. Long sentences need a written end date and a league-appointed enforcer who checks compliance.
