Split topic: Zipcar

I have a good web-browsing phone and love being able to extend the reservation on the fly, but I ran in to a little problem with it last time.

I purposefully chose one of the cars that had no other reservations until the late afternoon, figuring that I could extend if the vet visit went long... The vet visit did go long, of course, so I hopped on my phone to extend, but I got an error message indicating that the car was reserved for someone else. I flew back over to the garage, leaving my wife and cat at the vet (having no other choice), and pulled in to the garage at 1:29 (was supposed to return by 1:30). As I pulled in, I saw a woman and a stroller-child (the kind of kid big enough that he should probably be walking on his own, but isn't for some god-forsaken reason... but that's a whole 'nother subject...). The woman was clearly worked up, cell phone in hand, evidently calling ZipCar to complain about me for not returning early. The garage attendant (the very lax gentleman that I had to wait 15 minutes for, upon picking up the car 2 hours earlier) rushed out of his little office to lean over the hood of the car to verify that this was the car that she had reserved. They both shot me dirty looks, making me want to bitch both of 'em out, but I restrained myself. I mean, a) I got a late start because the garage attendant wasn't there- he was evidently out cruising with the friends that dropped him off after I had waited for 15 minutes, b) why would you make a reservation that butts up against someone else's reservation? Why not select one of the other cars available or at least allow a half hour? c) If you DO make a reservation that butts up against another, don't be huffy when the car is returned ON TIME. Boo hoo, you couldn't pick up your car early.

Meanwhile, there were two other ZipCars sitting there, at least one of them with the same hourly rate... wtf?
