so stopped at dairy queen today... the experience was just fine overall but I feel that I have no choice but to give this place one star for the reason below:
I WAS POISONED.... yes. poisoned.
Obviously not a lethal amount but I was served a blizzard that contained cleaning fluid in it... why you ask? An employee was midway through cleaning the blizzard mixer (they abandoned it for a bit) when mine was made. 9 bites in I was told to stop eating my ice cream IMMEDIATELY. I was not offered a refund. I was not  even given an apology. Sue?
