It depends on what I want to incentivize/limit. So for a group full of excited kids that liked interrupting constantly, the story teller lost a token for each interruption. This put an upper limit on how much other people could influence their story
And then resetting tokens after each story can help keep things balanced. For example, if one player got a large number of tokens for being interrupted a lot, that player is going to have more tokens than everybody else for the rest of the game.
But these are just improved changes that I like for my groups. Mileage may varry
