There's nothing inherently wrong with slushee -type drinks.
They're easy fun and tasty.
That's exactly why they are terrible for a holiday work party.
If you've ever had a blended Margarita or Pia Colada.
you know haw hard it is to know how much booze you're ingesting.
Mix that with amateur bartenders pouring unevenly and you have a sweet. icy recipe for disaster
