Returned a rental last night, and took a walk through the National lot. The green cone had been replaced with an orange cone. That gave me a laugh; but it was still the same game.
The cone aisle had only midsize cars, with one new Focus but mostly HHR's and Calibre's.
There was no shortage of cars on the lot. If your reservation was higher than midsize, the "greeter" would direct you to a car.
