Wow, the other reviews here might be from local renters, because I have rented cars several times here at Sky Harbor and the Enterprise operation is easily the worst at this airport.  You get to stand in line at one counter upstairs with every third golfer in the world, while three admittedly cheerful but way too slow employees work their way through the EIGHTEEN parties in line in front of me--I am not exaggerating, it was a weekday and there were EIGHTEEN people in line at this Enterprise counter in front of me, and the line took 30 full agonizing minutes to wind its way to me.\n\nThen, the upsells started.  Don't I want a class up from \"intermediate\" for $5 bucks a day more?  Even though the company was paying for this rental, I said no.   Don't I want this that and the other thing?  Am I sure I don't want to upgrade?  This car won't have electric mirror controls!  After painstakingly assuring the upseller that I had no intention of upgrading, he finally and regretfully gave me my contract and sent me to the escalator to go down to my car, where I found out I had to wait at YET ANOTHER COUNTER, this time to be chatted up by two more cheery, bustling employees.  \n\nYes, they offered me a bottle of water, but this was all taking way, way, way too long.  Another upsell attempt (when did the little Sentra become an intermediate?); fending off inquiries from the vaguely missionaryesque dudes at the counter about why I came to Phoenix and what line of work I'm in and do I golf; the second (actually third) guy finally walked me to my car, where we had to do a full pre-flight walkaround.  I mean, there was constant scribbling in contracts.  Jeeminy Christmas, this is taking 45 minutes at this point!\n\nFINALLY they let me go!  \n\nLook, this rental car center is TOO FAR from the airport, but that isn't Enterprises's fault.  But knowing that people are already annoyed with the bus ride and the queuing of the bus out front while the clock ticks up and the air traffic controller-like ground crew waves the bus into it's enormous dock out front, couldn't Enterprise do something to speed up the queue, the checkout process, and the getting-you-on-the-road part?
