Tech guy, WELL SAID. If you ever had to evacuate this dress code covers it all. It also allows those idiots whose ego requires them to travel back from a sun destination to a cold climate wearing shorts an option.. Picking up a family member the other day, 02:40 - 20C and people coming out from Customs in shorts. You would die of hypothermia if you had to evacuate away from the terminal building.
Debate the legal stuff all you want, this is likely the first post that brings common sense to this thread.
