While that's true, that's usually a fee they throw on independent of what the artist is actually agreeing to with the venue. So if you go on and agree you get 75% of the boxoffice and the venue gets 25% and you both need X amount of dollars for a sold out show to profit, you set that as your desired pricing, then Ticketmaster says ''OK cool $80 tickets, we agree to give you that'' then they turn around and sell the tickets at $250 and keep the rest.
