Why Bother With Percent Anyway?

After just wading into the basic idea of percent, I wrote this short story to help illustrate the benefits and power of using a standard reference frame to describe and compare fractional quantities. My number rockets made a few quick Oh Yeahs!  at the question for the first scenario about whether or not to be worried, but that certainty gave way with a few groans at the implication of the second scenario. Thank goodness for learning disequilibrium.
