The worst one I had was in China. A mountain who weighed in at 350lbs. His kit was in two bags that weighed 84lbs and he also had a set of golfclubs.
The rep let him go with the lot and two other Chinese pax were dropped.
He was typical of contractors then. They would carry there entire wardrobe around the world and expect to take it offshore with them; and in most cases there was no alternative.
