Well, not all of it - the damage or the unauthorized driver - but yes, I've made a reservation, waited in a long line (systems were down so everything had to be done by hand), completed the paperwork, dragged my luggage to the garage, and... NO CARS!
Not just no cars in my reserved catetgory, but no drivable cars period. Just one with locked doors and no key. And no staff. So back down to the counter where I interrupt the lone agent, who sends me back up to the garage and says there'll be someone up there. Nope. So I stood there yelling "help!" and finally somebody showed up with a single midsize car... with squealing brakes. By now it was 3:30 AM and I'd been awake about 24 hours, so I took it and left.
