I went through ATL immigration, customs and TSA Monday night, and there was no pre-check, but rather take off your shoes, take out your laptop and liquids, a screaming female guard, and then nude-o-scope and pat down treatment. For me this was the third time going through airport security in one day, and at 8:45 pm with less than an hour to make the last connnecting flight of the day over at T6 I wasn't amused.
The TSA agent insisted on patting me down. I broke my rule of not having anything to say to these creatures and asked him whether he enjoyed himself.
