do a market survey to see if there really is demand for the stuff. As long as the sale of soft drinks stays about where they project it should be, they will continue ONLY to offer the non-caffeinated varieties. They may consider it only after they see sales going down and know that such sales are going down because people refuse to buy the current soda but instead want caffeinated varieties. But it can't be a silent protest. You have to let them know that and there has to be more than a few dozens of angry caffeine junkies who refuse to buy sodas (and in protest, you also can't switch from buying sodas to buying bottled water - BYU will just think they are seeing a more healthy fanbase).
