Today I was LOCKED IN the parking of the IAH airport because their system was not working. I had and emergency and need to leave ASAP, and instead of opening the gates for people to leave they were asking people to stay in the massive cash lane !! I was at least 30 minutes waiting, until I finally talked to one of the group personnel (totally unprepared for the situation) that I had to go NOW, and she opened the gate for me. I had cash to pay but they were not letting anyone out, this is ABSURD !! I was late for my son's doctor appointment because of this caos in the parking today. No one can take you right to come and go, this is UNACCEPTABLE!!
