I have to park in this lot for work sometimes, and I paid the full amount, and STILL got a last warning towing sticker on my windshield. Whoever checks the meter at this lot is dishonest about who has paid and who hasn't. So, I would hate for someone to park there and pay and have their car towed. When I called the company to tell them I paid, the lady who answered pretty much said I was lying and was unwilling to believe me. Good luck to you all!
