Each club has a gear steward. They are responsible for the collection and washing.
At the sharks there is a list of what size jersey and what size shirts each player wears.
When they arrive each game the jersey shorts and socks are in numbered bags from 1-17 or whatever.
At the end of the Game the players were responsible for putting their gear back into each bag.
At the sharks we had 4 people who checked off all the gear was returned, turned the gear in the right and sorted it into jerseys socks and shorts. They were hen responsible for delivering the gear to the cleaners and picking it up ready for the next game. These guys were older and in sure they had been with the club since day 1.
This was the usual, unless players had requests like new socks every week, or only wanted socks they had worn and brought with them, or shorts 2 sizes too big.
