Pickle kiwi grape phosphate

So I was sitting at the bar when I commented to my soda jerk that Mac Alpine's is going to make me look soft because I can't seem to find anything on their menu that is bad. This set him on a mission.
He began by making me a pickle flavored soda which I liked (70 bottle caps) so he then made it a phosphate , which actually made it a LOT better (80 bottle caps) and since that again failed he added kiwi when made it slightly better (82 bottle caps) and finally he added grape to the mix which ultimately made it disgusting (30 bottle caps)
