The Housemates should get a smaller fee to go in and the rest of what they would of got should be spread out as a daily amount, they'd think twice about leaving then.

I'd say it would change their behaviour too, but I doubt that one as they each have different opinions as to what will keep them in.

Perez is going on saying he wants out, but is he hoping that if he annoys the public enough, they'll keep him in out of spite.

Anyways, link their fee to how many days they survive.
