Do they give a refund to customers who drive small amounts of miles on a rental even though they have "unlimited" miles available to them? Didn't think so...
I pretty much agree with you, but let's run with the other assumptions in this thread. We all know how much we like picking up a rental car that only has 100 miles on it. A car with 1000 miles on it is cause for disgruntled customers...causing us to go back to the rental office to look for something newer. If the OPs friend is consistently returning cars with ~big~ miles on them (relatively speaking), especially to the same location, that may be a hassle National isn't willing to put up with anymore.
Just a thought.
