My wife has been detained twice in Atlanta by idiot CBP agents. The first time by some younger guy looking to prove how tough or thorough he was. He claimed she was planning to overstay her allotted 90 days (out of 180) that she could stay visa-free. We (I wouldnt leave her side) were detained in a waiting area for an hour, and then called before a panel of three uniforms who examined her passport and tickets, saw she was within the rules, apologized and let her go. The second time, the CBP guy was himself an immigrant (Dutch Caribbean, from his appearance, accent and nameplate. This jerk claimed that my wifes fingerprints didnt match, despite our insistence that she had not replaced her fingers since the last time she had entered the USA. We had to wait 45 minutes, got called before the three man panel, all of whom looked at the problem, rolled their eyes, and apologized profusely for the first agents stupid attitude before sending us on our way. Atlanta for us is usually either smooth as silk or like walking in hot coals.
