For the first time going through airport security here in Memphis, things went smooth. Every other time that I have been through, the«greeter» would send half the people through the precheck line even if they weren’t precheck approved. This time it was only about 20%. It’s a good thing it was nice and early in the morning. This guy really needs to understand what precheck is if he is going to do this. He is wasting the time of the TSA agent who has to continually redirect people to the correct line.
