One month of carrying a chain wallet, visible chain, clipped to the belt, at all times including office wear and formal events. Nobody will say anything, which is what makes it unbearable. Micro-punishment perfection for leagues that prefer psychological warfare.
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.
