Once upon a time, there was bartender without a mustache, and nobody noticed him, and he just got people beers and never got laid and didn't know a damn thing about Chartreuse. Very sad story. The days of once upon a time are over. Today they've all got mustaches, and so many of those mustaches have wax. How did this happen? What does it mean? We asked our team of expert bartenders -- only one of whom has a mustache, even though it doesn't really count because he has all the other parts of a beard as well -- exactly what they think of this lip-proximate phenomenon.
