Not all dealers are built the same. I have worked at 5 dealerships in 28 years in 3 different cities. Everyone would top off fluids and check tires in the lane for free. I guess I have been fortunate in that way.
You pull up to the big door, it opens(or its open), you pull in the building, and you talk to an employee. This is how every dealer I have worked at operates. I will check tires and top fluids off, it is a great way to interact with customers, it goes a long way.
I take back my personal experiences.
