Today at PBI, they were looking over the belt and telling everyone to remove their shoes, including the woman in front of me wearing sandals that were flats with just a single strap -- def not part of any profile.
I went through in my sneakers like I always do and no one said a word. I did chat a little with the TSA woman pre-xray and it was clear I had been through security plenty of times (bags were put in based on my order, stuff all ready to go, etc). This is a stupid and inconsistent process!!
