The start of our experience with Thrifty was fine.  Got a great deal on-line through a third party.  Showed up to the counter and had to wait a bit but not long.  No hassle about extra fees or anything going through the rental process.  Went out to the garage to pick out a car.  We started loading all of our stuff into a car but then realized we actually thought a car a few spots down the row was more roomy.  So we moved everything to that car.  So we thought.  Here's where the trouble started.  We drove out of the garage with our rental that evening and the next morning we realized that we had left a laptop in the other car!  We immediately started calling all of the numbers for the Thrify desk at Sky Harbor.  NO ONE EVER ANSWERED THE PHONE.  Apparently there's no one at the desk on Sundays.  And the lost and found office isn't open at ALL on the weekends.  Because people don't loose stuff on the weekend????  I don't know.  Meanwhile, we're left wondering if someone has found our laptop or, worse, has driven away with it in their rental car!  We knew exactly which car it was left in, which spot it was parked in, etc.  All we needed was for someone to go out to the garage and see if it was still there but we had to wait.  We go through the process of filling out the on-line lost and found form on-line.  We resume calling on Monday morning, bright and early.  After many hours we finally get ahold of a person in the lost and found office who can only tell us that a) they did not find our laptop and b) the car is no longer in the spot in the garage (so it's probably been rented, with our laptop in it).  We can never get ahold of anyone at the rental desk nor can we reach the manager on duty (it goes to voicemail which is NEVER answered).  We spend many, many, MANY hours on the phone calling all kinds of Thrifty numbers - local, corporate, etc. - but keep getting the same run around about filling out the on-line form.  The problem, of course, is that the car that was rented is not our car and it may not even be returned to the same airport.  The lost and found process assumes that you left an item in the car that YOU rented and returned.  This is not the case.  If this car is returned to a different Thrifty location we will NEVER find this item because apparently there is no way to search through ALL of the lost and found offices on a national level.  Or at least there is no one at Thrify that is interested in doing this for us.  Over the course of 5 days, we NEVER got through to anyone at the counter or to the manage on duty, despite leaving several messages.  That's the bottom line.  NO ONE THERE GAVE A CRAP ABOUT OUR SITUATION.  Not renting from them again.
