I'm under the impression that this hack didn't really mean other clubs got less money. On the contrary, it seems to me that thanks to his actions (which resulted on the restrictions for all clubs being softened) caused all of the clubs to make more money with increasing lunch sales.
ah okay, I read it as if there were limited places and they acquired more by pressuring the people into needing them to make more, if there's no limit then awesome, I retract my distaste!
Oh there where limits in place. The school allowed one club to do a sale per week. That's one sale per week regardless of the club, and clubs that had a precedent generally took most of the dates allowed to do sales. After this, the school realized that more clubs needed more money and they now allowed more then one sale per week, and more than one club to do said sales per week.
