By the same token, could've introduced the "administration fee" to recover the cost of running the customer service desks, or the "cleaning fee" to receive a clean car.

The point is, all those costs together are simply the cost of doing business, they should be included in the rates together with the profit margin.

Anything else is a false advertising, and in a properly regulated market it shouldn't be legal.
