One of the things Old Dominion has spent alot of resources on is being able to accurately gauge how much it costs to handle individual shipments. They can figure out how much time it takes to handle on the dock, and how much time it takes to deliver. If the consignee needs special things like appointments, inside delivery, or fingerprinting, all this is taken into account and they price accordingly. The salesmen have very little wiggle room, plain and simple Old Dominion will not haul freight at a loss. Also they reweigh as many shipments as possible, and charge customers for the actual weight, not just what was listed on the BL.
Grizz.
