​Taco Bell should have a combo called “Taco Roulette” where you pay like $10 (depending on region) for 3 random menu items and a soda.

It could be literally any three menu items. It could be three of the same menu item. It could be three expensive items or it could be three cheap items, or any combination of those, decided by the computer. Also make it a big punishment if the workers choose to ignore the choices and just make what’s easy because that’s lame.
