Competative netfixing
A common "sport" played in the Dwarven Fishing Village of Blackstone. Children would compete with each other to see who could repair the most fishing nets in a day. The winning child got an extra stout of ale in their daily rations. Years later at the Monastery Ardrick realized this game, along with competitive rock hauling and competitive fish cleaning, were really just thinly disguised child labor rackets.
