Answer these questions, and put policies in place to deal with these instances, and freight can become a small profit center for you.
For ideas on policies, take a look at what
Maple Ridge Farms publishes to its distributors. Every charge on there is fair, in my opinion. (They make no mention of residential surcharges because they automatically bill residential book rate if shipping on their account--based on the majority of their shipments going to residential addresses.)
An even more exhaustive list of extra services can be found on the back page of their 2010 catalog. I'm hard pressed to think of another supplier that publishes a charge for "intercept".
