Do you speed a new hire along the on-ramp or make them wait at the rental desk?
I'm going to make a rather large assumption at the beginning here and that is you travel and sometimes you rent a car at the airport.
If you do this regularly you may be tempted to become a valued member of the loyalty program for the rental car company of your choice. When you do, what happens next is really quite astounding the next time you rent a vehicle from your chosen company.
