How long should a service test drive be?

Hi All,

Just had a car back from service at a dealer. How many miles would a dealer typically cover as part of a service?

Just an oil and filter service

The car was sent on a covered trailer to the main dealer and returned on one. While with the dealer the car has gained a few scratches and chips over the bodywork and wheels.
