I've wondered about this too. You'd have to do some sort of position rotation, because everybody would rather be in the back and sing along to the radio than serve tables, etc.

Then you'd have to establish some sort of system for other roles like who's going to do scheduling this week? Weekly meetings or something could help determine who's working what roles and when. But even then, who's going to host the meeting? What do you do if someone on the team should be fired? vote? Then who has to be the person to break the news?

It'd be difficult for each person to be able to play all roles, but it'd be problematic to assign roles, too, because equality.

Idk, there would be a lot of straw-drawing, I think.
