If he was offered a salary of $100 million per year, I'm sure the author wouldn't refuse it on the basis of a gym membership being part of the package. This example shows that the services he names have some finite value (perhaps zero or negative) which can be added to the salary value. A person considering a change in employment just needs to figure out what that value is, so you can put competing offers from different companies on the same scale.
