WTF is this even supposed to mean??? I have to attend a pretty high level meeting this week to re-write some protocols for dealing with chem/bio/nuke mass disasters (i.e., figure out how to quarantine you mofos when you catch swine flu) and the attire is "business casual". For military, we have ACUs and we have our Class A's and Class B's. I have no frickin idea what "business casual" means. Are sweaters ok? Tie, no tie? Tucked, untucked? Jeans? From what I can tell, business casual appears to mean khakis.
