So, here is a situation to ponder...
You're new to an area and playing in a competitive, but friendly local league event. You throw the low round of the day...but the final group takes another hour to come in and you have a family obligation and choose to leave and have a friend collect for you.
An hour later you find out that you can't collect due to the 'must be present to collect' unwritten rule--but the rule was never mentioned to the group before or during play.
Remember this was a local friendly, not a tournament. Is the player right in being angry that the coordinator:
a) never mentioned the 'must be present to collect' unwritten rule
b) withheld the payout
