I don't think the request for Memorial Day should be that big of a deal. After all, when you book a certain class of vehicle, you should get it. You get the seat you reserve on planes, the room you book in a hotel. Enterprise advertises smoke-free cars, so is that too much to ask? Now we all know that Enterprise doesn't care about customer service in the end, only about making profits--hence the only reason they use the just-in-time inventory. It's really quite simple, especially at the airport where there usually aren't open-ended rentals like for replacement...ERAC should keep better track of these rentals. If it doesn't have a car, don't let people reserve it. To get the car class you reserve, clean, smoke-free, filled with gas, and ready to go when it's your reservation time...imagine that...
