history: At dinner the other night, my family ordered three diet cokes.  They all came out a different shade from dark to light.  I was pretty concerned with the quality of the drinks when they were delivered. We ordered 3 diet cokes with dinner the other night_comma_ and they all came out a different shade of coloring!
current: Wow that is weird.  I love Diet Coke.  What was wrong with it?
next: I was concerned they were the wrong drink order, we lined them up and talked to the server and together figured out the syrup bag must be going empty!
