There’s a bar in my neighborhood that has a huge sign up that says “No Frosty Glasses” on it, presumably because people would ask for beer in one. While the idea of banning frozen glasses might seem like a stunt by a hipster bar, there’s actually a lot of good reasons to not drink your beer out of a frozen glass.
