Suppose that a friend asks you to drive him to the airport this weekend so that he can catch a flight. He pays you for the gas used driving to the airport and for the cost of parking the car at the airport while you help him in with his bags. He then declares that you are now even, since he has fully compensated you for any costs you incurred in helping him get to his flight. From your perspective, what aspects of the price of taking your friend to the airport has he omitted?

Implicit Imputed opportunity cost of time sacrifised while airport drop .

Explanation:

My friend asking me to drop at airport, & paying costs : gas used while driving, parking cost of car - has excluded certain price giving aspects.

He has included all the Explicitly quantified costs , whose payment is made to third person - like fuel & parking.

However, he has not included the implicit cost in terms of opportunity cost i.e other things sacrifised while going to drop him. Such costs payment is although not directly made to third person, but they still reflect a 'cost' as they reflect a gain sacrifised meanwhile.

In this case, it includes time sacrifised while going to drop friend at airport. That time could be used at work, which could have monetary benefits. So, this cost is eliminated to be evaluated by my friend.
