It is a very true fact that they can, also, another fact is that the rental company has to prove they did not have another rental...it does not matter that the customer might want a Buick over a Chevrolet.

If you are ever in the position that are going to charge you 'out of service' fees...question whether they did have another vehicle and make sure you tell your card company NOT to pay the charges.

Most insurance companies will cover a rental the same as your personal vehicle except for the 'out of service' fees.
