the current offerings and let BYU know that they will not buy soft drinks until caffeinated beverages are offered, will BYU acknowledge the demand exists. So the poll's results, regardless of their "validity", will carry absolutely no weight on what BYU does.
As long as a good percent of those who WANT caffeine continue to buy non-caffeine, BYU will fail to recognize any reasonable demand exists. BTW, the 83% number is not hard and fast number, it's only the % you initially quoted in your response. Until a large contingency of drink buyers stop "settling for" and buying the non-caffeinated drinks, BYU will not see a demand for drinks truly exists. That's not anything I learned in school from any professors other than what I learned in years of observation of just how BYU does things. Yes, BYU is weird and strange and wacky.
